Abstract:
The paper attempts to research the seismic behavior and mechanical mechanisms under repeated low-cycle loading of vertical connections in prefabricated reinforced concrete structures. Eighteen specimens were designed and tested, the test process and the mechanical mechanisms are studied, the seismic behavior of connections is analyzed, and the shear resistance formulas are proposed. The theoretical values based on proposed formulas are good agreement with test results. Under repeated loading, the shear resistance decreases, the connection ductility increases with connecting bar, but decreases with connection width. However, all the connections fail crisply with poor ductility. At sudden-cracking, the shear resistance increases with connecting bar, but changes nonlinearly with connection width. The resistance is composed of attributions of mechanism of diagonal-compressive column (MDCC) and mechanism of compressive friction action (MCFA). After sudden-cracking, the shear resistance is provided by weakened MDCC and dowel action of connecting bars (DACB). It increases with connecting bar and connection width.

Abstract:
Mathematical connections are connecting mathematical concepts and mathematical concepts with other sciences and problems of everyday life. Mathematical contextual problems can be used to view and build students' mathematical connections. The purpose of this study was to describe how the mathematical connection abilities of junior high school students when solving contextual problems on set material. The type of research used is qualitative descriptive research. Research data obtained through mathematical connection tests and interviews. Analysis of mathematical connection ability is divided into modeling connections, concepts, representations, and procedures. The results of this study indicate that high mathematical ability students make modeling connections by making mathematical models, conceptual connections by connecting many members of each set, and procedural connections by operating algebraic forms correctly, representation connections are not carried out because students rarely use Venn diagrams. Students who are mathematically capable are not making modeling connections, concept connections, representation connections, and procedural connections. Students with low mathematical ability do not make modeling connections, concept connections, representation connections and procedural connections

Abstract:
For ductile beam-to-column connectiosn in steel frame, beam local buckling is difficult and very costly to repair in any post-disaster reconstruction. Shape memory alloys (SMAs) in their austenite states have the ability to recover their original shape after experiencing large deformations. Steel connections retrofitted using SMAs can be endowed with intelligent characteristics. This paper investigates extended end-plate connections using long shank SMA bolts. The SMA connection is designed using a new methodology of avoiding beam local buckling and adopting the strong end-plate. The connection deformations are supposed to concentrate on the SMA bolts. In order to study the seismic behaviour of the connections, quasi-static tests were conducted on both the SMA connection specimens. The test results indicate that the connection can show high deformation capacity with the maximum interstory drift angles beyond 0.02 rad. However, the beam was remained elastic during test and the deformations of the SMA connection were recoverable upon unloading. The load-drift hysteresis loops are flag-shaped for the SMA connection. This indicates that the connection has moderate energy dissipating capacity.

Abstract:
A new detail is introduced for precast concrete beam-to-column moment connections. The detail consists of a connecting steel frame used to mechanically connect the threaded end protruding reinforcing bars from beam and column. The connection detail is made convenient to assemble where the erection method resembles that of steel construction. No idle crane time is necessary, since the connecting steel frame is designed to carry the beam's own weight. When the connection construction is completed, the joint functions as a moment resisting hard connection. The experimental testing program involved testing of twelve full-scale specimens in addition to a pilot test. Of the twelve tests seven are flexural tests, three are shear tests, and two are monolithic flexural tests for comparison. Modes of failure in the flexural tests were mainly due to rupture of tension reinforcement; however, premature slippage of the rebars may occur under certain conditions, but could be conveniently prevented. In the shear tests, diagonal tension crack failure predominated. If the connection parameters are properly selected, the connection will be capable of developing the beam's full plastic moment and undergo sufficient rotation before collapse. Key words: precast concrete, moment connections, connecting steel frame, stiffness, strength, ductility.

Abstract:
The mathematical connection is a crucial ability possessed by vocational high school students in solving problems by their field of expertise. Agriculture is a field of expertise that requires a lot of mathematical connection skills to solve various problems. Increasing the ability of students' mathematical connections can be facilitated by the teacher by constructing mathematical tasks in the agricultural sector. This qualitative research using the case study method describes the construction of mathematical tasks based on agricultural products and the mathematical connection ability of students in solving the task. Mathematical task construction is carried out by integrating agricultural product contexts and mathematical concepts. The mathematical task was used in Grade X Agribusiness Expertise students of Agricultural Product Processing. Data retrieval of students' mathematical connection abilities was carried out through tests, observation results, answer sheets, and interviews that focused on connecting contexts with mathematical concepts, connections between mathematical concepts, and connections to mathematical procedures. The results of the student data analysis showed that the ability of mathematical connections was hampered by the ability of the connection between mathematical concepts. It is necessary to increase student's mathematical connections by constructing mathematical tasks with various mathematical concepts.

Abstract:
The cold-formed thin-walled tube has been widely applied in high seismic fortification intensity region and post-seismic reconstruction area because of light quality, high strength and small deformation. But the connection mode and mechanical properties of beam-column connections still need further study. According to the "strong column and weak beam" seismic design principle and the thinking of control the position of plastic hinge, adding haunch slabs at the end of beam to reduce the number of repeated welding and avoid brittle fracture. Through the low cyclic loading experiment, four beam-column connections with welded haunch under different axial compression ratios have been studied, and connection’s hysteretic performance, energy-dissipating capacity, bearing capacity, rigidity and failure mode have been discussed. The result shows that: 1) the ultimate bearing capacity of connection with welded haunch is much great, and the energy dissipation capacity is very well, which can make this connection to absorb and consume great energy in earthquake. This connection can meet the need of seismic design very well. 2) The connection with welded haunch experiences much cycling time, has long yield platform after yield, has great cumulative energy-dissipating capacity and well ductility. 3) the final destruction of connection with welded haunch is caused by the beam’s local buckling. And the yield surface is almost located at the outside of connections. 4) The axial compression ratios has great effect on the hysteretic performance, bearing capacity and stiffness degradation for the connection with welded haunch.

Abstract:
In this paper, the behavior of steel plate shear wall (SPSW) in the reinforced concrete frame (RCF) has been studied numerically. Three different connections have been proposed to connect SPSW to RCF. In the first connection, fish plates, while in the second one, combination of fish plates and studs transfer forces between SPSW and RCF. In the third connection, there is no direct connection between the infill plate and RCF, and additional steel frame has been used for connecting of the infill plate. The results demonstrate that, load carrying capacity increases in all the specimens comparing the reference RCF. Investigating the formation sequence of plastic hinges in different specimens demonstrates that there is different sequence in the specimens with different connections.

Abstract:
Parallel strand bamboo is a composite material that demonstrates high strength and low variability compared to other timber materials. However, its use in bolted connections is limited by a tendency to fail in shear-out mode. One promising technique to prevent failure is the method of confinement, whereby the composite connection is confined laterally, inducing a compressive force perpendicular to the composite fibres, which increases the shear strength in the loading process. This paper investigates the confinement method and its effect on parallel strand bamboo connections’ strength and failure mechanisms through experimental tests and ANSYS simulation methods. It was discovered that bolted connection confinement reduces the propensity of shear-out failure by counteracting shear stresses. A comparison of graphical results revealed that confinement increased the ultimate tensile capacity of parallel strand bamboo bolted connections by up to 26%. Confinement also improved the consistency of the connection’s mechanical properties throughout the loading process. These findings assist in refining and optimising practical applications of parallel strand bamboo connections by using the method of connection confinement.

Abstract:
Timber connection capacity, in case of beam-column joint connection provides significant impact on the wooden building structures. Strength and stiffness of timber connections using reinforcement technique of wooden building structures have not been studied intensively. This paper studies the use of nails and modified-washer to improve wood connection’s performance. The experimental tests were conducted in the laboratory by comparing the partial connection between test specimen timber without reinforcement (standard type) and the reinforcement (PRP type). The testing was conducted based on partial connection beam-column joint test using Universal Testing Machine’s with a modified holder. Wood studied includes Meranti (Shorea spp.) and Mersawa (Anisoptera spp.). PRP type connection was using nails and modified-washer strengthening, and standard type connection was using a classic washer. Parameters studied were strength and stiffness of the connection, reviewed both: proportional limit load and ultimate limit load conditions. Result obtained from this research indicates that the use of nails and modified-washer make a positive contribution to improving the performance of the beam- column timber joint connections, in terms of strength capacity (both of proportional limit and ultimate limit loads) and stiffness capacity (displacement ductility ratio). Meranti beam-column timber joint is more brittle than Mersawa beam column timber joint, it has an impact on the results. PRP-type of Mersawa timber connection produces a higher ductility than the standard type, while the PRP-type of Meranti timber connection produces a similar ductility to the standard type.

Abstract:
In practice, bridge foundations and pier columns are usually constructed with cast-in-place concrete. Precast columns are currently widely used in highway bridges in China, which can save construction time and improve concrete quality. The connection between precast bridge columns and the foundation can affect how forces transfer from one to the other. This paper investigates using external sockets to form a connection between the bridge column and foundation. This method can accelerate the bridge construction time with the additional advantages of improving the orientation and creating a large erection tolerance. Two types of connections are presented and tested to investigate the behavior of the column-foundation connections and find a more suitable way to use external socket connections. The experimental results show that the column-foundation connection design satisfies the design requirements. The results also show that roughening the column surface within the external socket is more effective at connecting the column to the foundation when using an external socket compared to attaching a steel plate on the column. The experimental results are validated with a finite element analysis, resulting in a proposal regarding the column-foundation connection behavior as well as design recommendations for the external socket connection.

Abstract:
This study elucidated the mechanical performance of different connections used in orthogonal ribbed beams made of poplar laminated veneer lumber (LVL). Three types of connections (namely, U-, T-, and L-shape) were fabricated and used to connect the second beam and the middle part of a main beam to form an orthogonal rib beam. A concentrated load was applied to the intersection between the main beam and the second beam. The results showed: (1) all three types of ribbed beam connection specimens showed good connecting performance and the ductile failure, including the pull-out of partial self-tapping screws, crushing of LVL at the end of the ribbed beam, and connection failure; (2) the variation of load capacity of JD2-type specimens was approximately 3.2%, which was smaller than that of the JD1- and JD3-type specimens, slightly less than 10%; (3) the ultimate bearing capacity of a connection specimen was proportional to the number of self-tapping screws; and (4) the mechanical performance of the U-shaped connection specimens was worse than that of the L-and T-shaped connection specimens. The L-shaped connection was recommended due to its better mechanical performance, simpler configuration, and more convenient fabrication.

The grout sleeve connection offers important complement to traditional steel tube connections and is increasingly applied in structures. To acquire the connection’s behavior under eccentric cyclic load, study and tests were conducted at Tongji University on two specific types of grout sleeve connections which were identical except for some construction measures. The load-strain curve, load-deformation curve, elastic limit bearing capacity and stress-strain distribution of each specimen are obtained as results. Those results indicate that this kind of connection has good bearing capacity and stiffness, and those behaviors can be efficiently improved through optimizing its construction measures.

Abstract:
Precast column foundation connection is one of the critical connections under reverse cyclic loading, and the present study focuses on this connection. Three types of connections were considered, such as (i) base plate connection, (ii) pocket connection, and (iii) grouted sleeve connection. All the above connections were designed, and experimental investigation was carried out on 1 : 2 scaled models by subjecting the column to lateral reverse cyclic loading. Displacement-controlled loading pattern has been adopted for the testing of the specimens. The structural response of the connection was studied for their (i) load-displacement hysteresis behaviour, (ii) stiffness degradation, (iii) energy dissipation, and (iv) ductility. The results were then compared with that of the monolithic connection. The precast connection was more ductile, and the energy dissipated by the pocket connection was high compared to the base plate and grouted sleeve connection. The ductility and the load-carrying of grouted sleeve connection were small compared to other connections. The results of the study showed the precast column foundation can be used in seismic prone areas.

Abstract:
Based on the concept of strong connection and weak member, mechanical behaviors of the new reinforced dog-bone connections are compared. To new reinforced dog-bone connections, weakening flange at a certain distance away from the beam end and increasing weld area in the beam end. This improved connection can make the plastic hinge be far from the beam-column connection with stronger bearing capacity and better ductility. A nonlinear finite element analysis of the three forms of connections such as dog-bone connection, cover-plate reinforced dog-bone connection, and flange reinforced dog-bone connection conducted by ABAQUS. The results demonstrate that the energy dissipative and ductile capacity of the new reinforced dog-bone connection is strengthened effectively because of the plastic hinge forming far from the beam-column connection, and the carrying capacity of the new reinforced dog-bone connections are greater than dog-bone connection. By contrast, flange reinforced dog-bone connection is exceed to cover-plate reinforced dog-bone connection, for that the strengthened flange can resist the bending resistance better.

The Shen connection cannot be obtained by using Matsumoto's processes from the other well-known connections. Hence Tayebi–Najafi introduced two new processes called Shen's and -processes and showed that the Shen connection is obtained from the Chern connection by Shen's -process. In this paper, we study the Shen's - and -process on Berwald connection and introduce two new torsion-free connections in Finsler geometry. Then, we obtain all of Riemannian and non-Riemannian curvatures of these connections. Using it, we find the explicit form of -curvatures of these connections and prove that -curvatures of these connections are vanishing if and only if the Finsler structures reduce to Berwaldian or Riemannian structures. As an application, we consider compact Finsler manifolds and obtain ODEs.

Abstract:
The paper aims to study options for connecting belt elements from a profiled sheet, to develop a technology for manufacturing support units and to determine their load-bearing capacity by testing nodal elements with connecting sheets using electric rivets and soldering pre-rolled profiled sheets. An experimental study of nodal elements was performed in a vertical position on a test bench. Fragments of the support assembly with a seam-soldered connection and with the connection of belt elements using contact spot welding were tested. It is shown that seam-soldered joints provide the necessary strength thus being suitable as a basis for the flawless manufacture of an experimental unit. For welding connection, two options of the support unit were considered, i.e. with plastic support ribs and without ribs. The junction of profiled sheets using electric rivets is more technologically advanced than a seam-soldered joint. The conducted tests elaborated the proposed design solution and the method of manufacturing the connection of profiled sheets (support units). Tests of operability, reliability and strength of this junction with various connections were carried out.

Abstract:
Abstract Cold-formed steel (CFS) sections have gained acceptance as primary elements in steel frames due to their exceptionally high strength to weight ratio. The main purpose of this research is to study the behavior of the apex joint in portals frame when subjected to monotonic vertical load. Numerical models for apex connections are developed using a finite element program to study the behavior of the connection. The numerical model is first verified by comparing its results with available experimental and numerical results. After the verification, the effect of several parameters on the connection performance was investigated. The parameters included the effect of the connecting gusset thickness and length as well as the effect of the distance between bolts. Moment-rotation relationships for different CFS apex connection numerical models were analyzed. The numerical models showed that the most significant modes of failure were gusset plate or beam web buckling. Increasing the distance between the two connected sections decreased the connection moment capacity, whereas increasing the thickness of the connecting plate enhanced the moment capacity.

Abstract:
The strong column-weak beam principle, one of the earthquake resistant building design theories, require the connection area to be strong enough so that the plastic hinge forms in the beam. One of the proposed solutions is to strengthen the column-beam connection zone in steel connection with haunches. This study aims to look at parametrically behavior of column-beam haunched connections under the 100mm vertical displacement controlled loading using the finite element method. To obtain this, a total number of 21 finite elements model with 15, 30, and 45 degrees angles and 6 various stiffener types has been modeled by ABAQUS software. The research later discussed behavior of underlying components of haunch connections models such as the load-displacement curve, bearing capacity, extended end plate bending, stress distribution, and the position of the plastic hinge's development after finite element analysis. The study found that decrease in haunch angle improve the connection's bearing capacity, while in this case, the failure modes and plastic hinges will occur close to the joints which does not meet the code requirements. The article concludes that the 30-degree haunch angle is the most appropriate one in haunch connection and the three parallel and K-stiffeners is the most suitable reinforcement type for the haunched connections.

Abstract:
A novel method to improve the robustness of steel end plate connections is presented in this paper. Existing commonly adopted techniques alter the stiffness of the beam or the end plate to improve the connection’s robustness. In this study, the robustness is enhanced by improving the contribution of the bolts to the rotational capacity of connections; the higher the bolts’ elongation, the higher the rotational capacity that can be achieved. However, the brittleness of the bolt material, combined with its small length, results in negligible elongation. Alternatively, the load path between the end plate and the bolts can be interrupted with a ductile element to achieve the required elongation. This can be achieved by inserting a steel sleeve with a designated length, thickness, and wall curvature between the end plate and the washer. The proposed sleeve should be designed so that its ultimate capacity is less than the force in the bolt at failure; accordingly, the sleeve develops a severe bending deformation before the failure of any connection components. Using a validated finite element model, end plate connections with various parameters are numerically investigated to understand the performance of the sleeve device. The proposed system substantially enhances the rotational capacity of the connections, ranging between 1.37 and 2.46 times that of the standard connection. It is also concluded that the sleeved connections exhibit a consistent elastic response with the standard connections, indicating the proposed system is compatible with codified elastic design approaches without modification. Furthermore, for a specific connection, various ductile responses can be achieved without altering the connection capacity nor configuration.

Abstract:
Threaded pipe connections are commonly used to connect risers, tendons, drill pipes and wellcasing strings. In these applications fatigue resistance plays an important role. A large variety of patenteddesign features exist, all claiming to improve the connection’s fatigue life. However, patent documents onlycontain claims and numerical or experimental data about these connection’s performance is generally notpublished. This makes it hard to make a quantitative comparison between different designs. In this study anoverview is given of fatigue resistant threaded connections. Two major methods to improve the fatigue lifeof a connection were identified. First of all, local stress concentrations can be reduced by optimizing thegeometry of the threads. Second the global shape of the connection can be optimized to obtain a moreuniform load distribution.Using a parametric finite element model, different designs were compared. The connections were modelledby a 2D axisymmetric geometry with non-linear material properties and elaborate contact conditions.Selected designs have been subjected to experimental tests in a four-point bending fatigue setup. Theexperimental tests serve as a validation for the results of the numerical simulations. It was found that themultiaxial stress distribution at the thread roots is the defining factor for the fatigue life of the connection.Nevertheless, these stresses can be changed by the global geometry of the connection. It can beconcluded that the fatigue life of threaded connections is determined by a combination of global and localaspects which should both be analysed for fatigue life calculations.

Abstract:
Variability is an important but neglected aspect of connectional neuroanatomy. The quantitative density of the ‘same’ corticocortical or thalamocortical connection may vary by over two orders of magnitude between different injections of the same tracer. At present, however, the frequency distribution of connection densities is unknown. Therefore, it is unclear what kind of sampling strategies or statistical methods are appropriate for quantitative studies of connectivity. Nor is it clear if the measured variability represents differences between subjects, or if it is simply a consequence of intra–individual differences resulting from experimental technique and the exact placement of tracers relative to local spatial and laminar variation in connectivity. W e used quantitative measurements of the density of a large number of corticocortical and thalamocortical connections from our own laboratories and from the literature. V ariability in the density of given corticocortical and thalamocortical connections is high, with the standard deviation of density proportional to the mean. The frequency distribution is close to exponential. Therefore, analysis methods relying on the normal distribution are not appropriate. W e provide an appendix that gives simple statistical guidance for samples drawn from exponentially distributed data. For a given corticocortical or thalamocortical connection density, between–individual standard deviation is 0.85 to 1.25 times the within–individual standard deviation. Therefore, much of the variability reported in conventional neuroanatomical studies (with one tracer deposited per animal) is due to within–individual factors. W e also find that strong, but not weak, corticocortical connections are substantially more variable than thalamocortical connections. We propose that the near exponential distribution of connection densities is a simple consequence of ‘patchy’ connectivity. W e anticipate that connection data will be well described by the negative binomial, a class of distribution that applies to events occurring in clumped or patchy substrates. Local patchiness may be a feature of all corticocortical connections and could explain why strong corticocortical connections are more variable than strong thalamocortical connections. This idea is supported by the columnar patterns of many corticocortical but few thalamocortical connections in the literature.

Abstract:
One of the newest steel beam-column joints to replace conventional welded connections, post-tensioned connection steel is with the upper and lower angles. In this connection are high-strength steel strands that parallel beam web and angles between beams and column. Actually high resistance strands and upper and lower angles respectively are provider centralization properties and energy dissipation capacity of the connection. The benefits of post-tensioned steel can be used in connection with the centralization and lack of relative displacement (drift) persistent, stay elastic core components such as connecting beams, columns and fountains connection, appropriate initial stiffness and joint manufacture with materials and traditional skills. . In this study, numerical modelling in Abaqus software, the results of the analysis were compared with the results of laboratory samples and the results showed that the two together are a perfect match. After validation, parameters influential centrist connection then pulled the thick angles in three numerical models were evaluated. The results show that by increasing the thickness of the angles, increase energy dissipation capacity and ductility connection and the β₁ value does not experience tangible changes with changes in angle thickness.

Abstract:
Interference connection is an effective method for improving the fatigue life of bolt connections. In this paper, a new method of interference connection was designed based on the shape memory effect of shape memory alloy. Using the method of numerical simulation, a finite element model was established to analyze the stress–strain rule of the bolt and the hole wall under different interference fit sizes. The results show that the stress concentration is formed at the orifice of the connecting plate. When the interference fit size is less than 1%, the connection hole has elastic deformation. When the interference fit size is 1.5%, the hole wall has plastic deformation. When the interference fit size is 2.5%, the maximum stress on the connecting plate is close to the tensile limit of the material. If the interference fit size continues to increase, the strength of the connection structure will be damaged. The connection experiments with different interference fit size were designed, and the interference force was calculated by the pull-out force. The experimental results were compared with the numerical simulation results. The change trend of the interference force with the interference fit size is consistent, which verifies the rationality of the finite element simulation.

Abstract:
The purpose of this study was to describe the process of students' mathematical connections in solving mathematical problems in terms of learning styles. The type of research used is descriptive research with a qualitative approach. The research subjects were six students consisting of two students who have a visual learning style, two students who have an auditory learning style, and two students who have a kinesthetic learning style. Student learning style data were collected through learning style questionnaires, while student connection process data were collected through mathematical connection test sheets and interviews. Data credibility is done by triangulating sources and methods. Data from the six subjects consisting of two students for each of these learning styles were described and categorized from the same, different, and specific views. The subjects obtained from the results of the learning style questionnaire were compared using the results of the mathematical connection test and interviews. Data analysis was guided by four steps to solve Polya's problems and was carried out in three stages, namely data condensation, data presentation, and conclusions. The results showed that there are differences in the mathematical connection process carried out by students who have visual, auditory, and kinesthetic learning styles in the step of understanding the problem. However, there are similarities in the mathematical connection process carried out by students who have visual and kinesthetic learning styles at the step of compiling a completion plan and checking again. while students who have a different auditory learning style from students who have visual and kinesthetic learning styles in implementing the completion plan and re-checking. The process of mathematical connection of students who have an auditory learning style at the step of checking back cannot be seen, because these students do not take this step when solving problems. Researchers suggest that teachers need to accustom students to connecting mathematics both internally and externally and pay attention to the emphasis of the material given to students so that students' mathematical connections are more developed. because the student did not take this step when solving the problem.

Abstract:
The present study was aimed to investigate the strength and ductility of welded flange plate (WFP) connections. Using the FE method, 52 WFP connections with different beam overall depths and beam flanges/web slenderness ratios were analyzed. Fragility curves indicated that, for a WFP connection which is designed based on the seismic codes, its strength is of more concern than its ductility. In addition, limiting the width-to-thickness ratios of the beam flanges and web plates to 0.3E/fy and 2.45E/fy, respectively, may not always lead to the achievement of adequate connection’s strength and ductility. Proposed theoretical formulas and artificial neural network- (ANN-) based models developed in this study were able to adequately predict the connection strength.

Abstract:
In this paper, we analyze the diffusion limit of a discrete-time queueing system with constant service rate and connections that randomly enter and depart from the system. Each connection generates periodic traffic while it is active, and a connection's lifetime has finite mean. This can model a time division multiple access system with constant bit-rate connections. The diffusion scaling retains semiperiodic behavior in the limit, allowing for both short-time analysis (within one frame) and long-time analysis (over multiple frames). Weak convergence of the cumulative arrival process and the stationary buffer-length distribution is proved. It is shown that the limit of the cumulative arrival process can be viewed as a discrete-time stationary-increment Gaussian process interpolated by Brownian bridges. We present bounds on the overflow probability of the limit queueing process as functions of the arrival rate and the connection lifetime distribution. Also, numerical and simulation results are presented for geometrically distributed connection lifetimes.

Abstract:
This research work presents new details for moment connections in precast concrete structures satisfying both design and practice criteria. In this paper the results of the numerical study on the connections are presented. For the analysis, the ANSYS software is selected because of its diversity in nonlinear analysis. By calculating the monotonic load-displacement curve of each connection, the connections are evaluated for their stiffness, strength, and ductility. The compressive strength of the connection concrete is taken to be 30, 35 and 40 MPa, for each round of analysis. The results of the analysis show that the proposed connections are stiff enough to be moment resisting and to be emulating an equivalent monolithic, or basic connection. It is illustrated that the connections are stronger but somewhat less ductile than the basic connection regardless of the concrete strengths examined. Moreover, it is shown that in each precast connection while increasing the compressive strength of concrete does not affect the connection stiffness considerably, it increases the ultimate load and ductility of the connection. As a main result of this study, the suggested connection details are categorized based on their stiffness, strength, and ductility. The suggested connections can be used in moment resisting precast concrete buildings based on the desired strength and ductility.

Abstract:
In this study, a novel prefabricated light-steel beam–column connection consisting of a thin-walled rectangular hollow section column and two cold-formed steel truss beams is proposed and investigated by carrying out experimental tests. Eight cruciform beam–column connection specimens with different configurations are fabricated and tested to failure under monotonic static loading. First, failure mode and the loading–displacement curve of each specimen are investigated. Consequently, the effect of three variables, including truss-beam configuration, truss-beam type, and with or without sleeve tube reinforcing the column, on the static bearing capacity of the proposed connection and the deflection of the truss beams are investigated. It is found that plug welding the sleeve to the column can significantly increase the static bearing capacity of the proposed connection. In addition, fillet welding connecting the column and the channel connectors to accommodate the end of the truss beams is crucial to the static bearing capacity of the proposed beam–column connection. Because beam–column connections with single-truss beams have a higher load-bearing capacity and require less material and assembly work, it is recommended to adopt this type of configuration for the proposed connection.

Abstract:
Experiments and analyses were conducted to address concerns about performance of reinforced concrete connections with shallow, wide beams subjected to lateral earthquake loading and to compare behavior of wide beam connections to that of conventional connections. Two wide beam-column-slab connections and one conventional beam-column-slab connection were subjected to cycles of reversing lateral displacements up to 5% drift. The conventional beam and wide beam connections exhibited similar overall load-displacement behavior, with similar beam plastic hinge development. The wide beam connections dissipated almost as much energy as the conventional beam connection and had greater slab participation and less joint and beam shear cracking than the conventional beam connection. Experimentally determined wide beam connection stiffness was closer to the conventional beam connection stiffness than had been predicted. Refined models were developed, with features such as rigid end offsets for wide beam connections, to better represent observed behavior. Nonlinear models were also developed that accurately captured differences in energy dissipation as well as stiffness.

The theoretical analysis indicated, reduced beam connection’s hysteretic curve is more plumpness in shapes, have no significant pinch phenomenon, spindle shape, so the energy dissipation is better. From the view of fracture toughness, the weld joint’s fracture toughness is basically the same between dog-bone connection and traditional connection, the curves of weld crack tip’s biggest stress intensity factor as well as energy release rate about the two types connection are separately overlap, but at the middle of reduced beam section compared with the same place at the traditional connection, crack tip’s biggest stress intensity factor as well as energy release rate are significantly increased, when the initial crack length 3mm is assumed at the middle reduced beam section and the same place at the traditional connection, the reduced beam section connection’s nominal stress when reaching the material toughness KIC, it is 17% lower than traditional connection, in stress developing process, the middle of reduced beam section’s stress is biggest and it can reach material toughness. So the reduced beam connection can play a role as fuse, realize strong joints weak pole design concept.
