Abstract:
Aiming at the importance of the microcosmic topography of connecting surface and bolt assembling technique to the bolt connection performance, the fractal characteristic of bolt joint rough surface is studied based on the power spectrum of its micro surface profile. Fractal models of 2D and 3D rough surfaces are presented by W-M function and the 2D and 3D bolt joint rough surfaces are reconstructed. Imageware and Pro/e are used to build the bolt connecting model based on the real rough surface presented by W-M function. The preload is imitated by the PREST179 element. The finite element transient analysis is used to imitate the speed and force size of the bolt tightening. The relationship model between tighten speed, preload size and connecting performance whose target is contact stress is presented based on the finite element analysis results. According the model, the single bolt precise assembling technique is obtained.

Abstract:
This article proposed an analytic and finite element-combined modelling method for the investigation of temperature effects on bolt loads and variation in a bolted flange for subsea pipeline connection. With this method, the preloads of bolt in the bolted flange assembly were investigated under different medium liquid temperatures in the pipeline. The simulation results illustrate that the deviation of bolt loads can be increased due to the medium liquid temperature increasing. The final bolt load deviation increases along with the increasing of the initial deviation of bolt preloads in a constant medium liquid temperature. The final distribution of bolt loads can be affected by the initial condition of the bolts. When bolt preloads are staggered, the variance of the final bolt loads is minimized; when the bolt preloads are axisymmetric, the final bolt load variance is the maximum.

Abstract:
Mine earthquake, as an underground disaster that occurs frequently, has a great impact on coal mine roadway and support. The stability analysis of the bolt support in roadway under different mine earthquake magnitudes is a key issue to be solved urgently in mining fields. This paper attempted to simulate the occurrence state of mine earthquake with explosive blasting process and verified it with actual coal mine microseismic monitoring data. ANSYS/LSDYNA software was used to analyze the impact of magnitude and location of mine earthquake hypocenter on the stability of bolt support and the dynamic stress characteristics of bolt. The results showed that with the increase in source energy of mine earthquake, the damage location of bolt mainly appears in the front of bolt and the loading position has no obvious change, but there is stress wave superposition effect, which deepens the damage of bolt. The bolts in the middle of the lane and the middle of the roof are greatly affected, so the support strength should be strengthened in these places. In addition, this paper compared the safety factor of bolt and the supporting effect of different schemes from three aspects such as roof subsidence, axial stress of bolt, and safety factor of bolt and then put forward a more economical and effective supporting scheme.

Abstract:
The present paper investigates the impact of bolt distance, bolt diameter, and the number of bolt rows on the bending performance of timber–steel composite (TSC) beams. This study aims to facilitate the application of bolt connections in assembled TSC structures. Composite steel I-beams were designed with timber boards connected in the upper section with bolts. Three-point static bending tests were conducted on nine timber–steel composite beams divided into four groups (L1, L2, L3, and L4) with varying bolt arrangements. The destruction mode, ultimate bearing capacity, ductility coefficient, load–midspan deflection curve, and load–midspan strain curve of each specimen were obtained. In addition, the destruction mechanism, the quantitative relationship between the bolt area ratio and interfacial slip, and the ideal bolt area ratio were identified. It was found that when the midspan deflection of the timber–steel composite beam approached the prescribed limit, the main failure mode can be explained as follows: The top surface of the boards of all the specimens had longitudinal local splitting, except L1, which had fewer bolts and no obvious damage. Moreover, due to compression and because the stress at the lower edge of the I-beam entered the flow amplitude stage, some of the specimens were crushed but were not pulled off. The composite beams had high flexural load capacity and ductility coefficient, and the maximum relative slips of the timber–steel interfaces were in the range of 2–6 mm. It was also found that the maximum slip of the interface and the ductility coefficient decreased steadily as the bolt area ratio increased, while the specimen’s flexural bearing capacity increased. The optimal bolt area ratio was determined to be 8 × 10−3. Using the total bolt area, we designed the arrangement of the bolts on the board. For convenience, multiple bolt variables were converted into one bolt variable. The longitudinal distance of the bolts had a greater impact on the slip, and the bolt diameter had a smaller impact. The theoretical values of total relative slip were found to be in good agreement with the experimental results, which were based on the superposition of the relative slip equations with varying bolt distances. The effective bolt area ratio and the formula of the relative slip of each segment can provide instructions for the arrangement of bolts and the control of the relative slip of intersections in engineering practices.

Abstract:
In practical engineering, for instance the aerospace aircraft and engine industry, fastener connection is a very common joint structures, the current engineering typical strength analysis for bolt connection structure doesn’t include bolt bending analysis. In the engineering research and design phase, if the bolt connection plate is too thick or it contains shims or spacers that cause the bolt itself to be too long, then bolt bending failure analysis is also necessary. The bolt bending analysis is a complex failure mode, there is no unified analysis method for effective assessment for it. This paper introduces an improved calculation method which is proposed to specifically calculate the bending load of the bolt according to the force characteristics of the bolt for bolt bending analysis.

This degree project is a verification of a hand made calculation made by Semcon CAE inGothenburg, Sweden. The main purpose has been to investigate how loads in a pre-tensionedbolt appear and how material displacement and contact pressures in the nuts affect bolt joints.A FEM-model has been created to imitate the reality as much as possible this to verifySemcon’s calculations. The result of the FEM-model has been compared with the result fromSemcon report 87-082-008, see appendix 2. Thus the Semcon original report has beenverified.The results between the Semcon report 87-082-008and the FEM calculations can be seen inchapter 2 and appendix 1.The basic data of the degree exam is the Semcon report and is the starting point of the wholeproject. All data regarding dimensions, geometry, materials and so on is based on the datafrom the Semcon report.A fatigue analysis based on the FEM-results was not conducted. This was due to thesimilarities in result between the previous Semcon report and this study

Abstract:
This dissertation presents the results of testing to determine the load-slip characteristics of single-shear single lag screw connections subjected to monotonic lateral loading parallel to grain. Of particular importance was the comparison of experimental capacity and 5% offset yield load resistances to load resistances as predicted by the American Forest & Paper Association's (AF&PA) publication General Dowel Equations for Calculating Lateral Connection Values, Technical Report 12 (TR-12). Additionally some other tests were conducted, including fracture, tension strength perpendicular-to-grain, lag screw connection inking, dowel embedment, specific gravity and moisture content. The results for the testing program are presented. Four hundred and forty eight lateral tests were conducted on lag screw connections. Each connection was comprised of a 2 x 6 x 14 in. long wood main member, 1/4 in. thick steel side plate, and a single lag screw. The parameters of interest were specific gravity, lag screw diameter, and pilot hole diameter. Two species of wood, Douglas-fir and spruce-pine-fir, three lag screws diameters, and three pilot hole diameters for each species of wood were implemented. Models were developed to predict lag screw connection capacity and 5% offset yield and are contained herein. Models were based on results from connection and inking tests and mechanical analysis. Recommendation for ASD and LRFD design values were derived from connection test results for connections that used AF&PA's National Design Specification for Wood Construction (NDSb) specified pilot holes. Using fracture mechanics results, work was performed to determine the effective load required to crack and separate fracture surfaces of wood main members due to the installation of lag screws with varying pilot hole diameters.

Abstract:
Les assemblages à brides boulonnées munis de joints d’étanchéité sont les systèmes de raccordement les plus répandus entre les différents éléments des réservoirs sous pression. Ils sont largement utilisés dans l'industrie chimique, pétrochimique et nucléaire. Ce sont des structures simples et des assemblages démontables. Ce qui les rend plus attractifs pour connecter des équipements sous pression et la tuyauterie. En plus des risques de fuite, ils ont besoin de maintenance en cours de fonctionnement au cas où les boulons doivent être resserrés ou dévissés pour être remplacés. Bien que les arrêts de fonctionnement coûteux soient à éviter, l’entretien en fonctionnement expose l'opérateur à un risque potentiel, car le desserrement d’un boulon peut produire un déséquilibre de la contrainte de compression sur le joint d’étanchéité entraînant un contact local du joint d’étanchéité en dessous d’une certaine valeur critique, provoquant une fuite majeure et de ce fait pouvant mettre en péril la vie de l'opérateur. Cette proposition aborde la question de la variation de la déflexion du rebord de la bride afin d'enquêter sur le déséquilibre de la contrainte de compression dans le joint lorsque les boulons sont soumis à une modification de charge en fonctionnement. Cette étude peut être utilisée pour aider à limiter l'augmentation de la charge de serrage ou le nombre maximum de boulons qui doivent être remplacés en même temps et identifier les boulons qui ne peuvent pas être remplacés en service. L'objectif de cette étude est de développer une approche théorique pour identifier et analyser les effets de la charge précontrainte et de la pression sur les assemblages à brides boulonnées afin d’obtenir l'espacement optimal entre les boulons en fonction de la variation de la contrainte de compression sur le joint d’étanchéité. Notre recherche comprend trois parties. La première partie qui est une méthode analytique basée sur la théorie de la poutre circulaire reposant sur une fondation élastique linéaire, sera développée pour prédire la distribution circonférentielle de la contrainte de compression sur le joint d’étanchéité. Des modèles éléments finis de brides boulonnées symétriques seront créés pour valider cette analyse. Une comparaison des résultats d'études antérieures est nécessaire pour valider la solution analytique linéaire. Ensuite, la deuxième étape de cette recherche consiste en une approche qui a été construite à partir de la théorie de l'anneau sur le comportement d’une fondation non linéaire élastique, permettant d’obtenir des résultats plus précis. La solution non-linéaire doit être validée avec une analyse par la méthode des éléments finis. Dans la troisième partie, un modèle de régression linéaire pour des brides boulonnées sera proposé pour une procédure de calcul d’espacement de boulons. Ce travail aidera les services techniques sur la conception, la maintenance et l'exploitation des réservoirs sous pression et systèmes de tuyauterie.

Abstract:
The aim of this thesis was to investigate the effect of clearance and tolerance in bolted joints when there is a mismatch between the bolt holes. A parametric study with seven different cases was analyzed in this project; four double bolt configuration and three triple bolt configuration, with variation of the size of the bolt hole misalignment, the diameter of the bolt and the thickness of the plates. All analyses were performed with the aid of the FEM commercial software Abaqus, all the models were modelled with 3D brick elements. Despite bolted connections being subject of several investigations, no study about this matter for structural engineering purposes had been performed before. The results indicate that for connections with a low number of bolts a misalignment of the bolt clearance can cause a serious reduction in the ultimate bearing capacity of a joint and it indicates that the Eurocode 1993 1-8 might be overestimating the ultimate bearing capacity for some cases.

Abstract:
In health economics benefits are often measured in terms of quality adjusted life years (QALYs), an index that combines the length of life and the health related quality of life (HRQoL) of patients. HRQoL is usually estimated using generic preference based measures (GPBMs). To ensure comparable decisions it would be recommended to use only one GPBM in all assessments, but this is not always appropriate due to validity and responsiveness problems of these measures. When this happens, bolt-ons represent a potential solution. Bolt-on research is at an early stage, and the process of how to identify and select bolt-ons is still unclear. To address this gap, this thesis examines methods for identifying and selecting bolt-on dimensions, using the EQ-5D as a case study. This thesis summarizes the results of four studies. The first study examined the performance of the 5 most commonly used GPBMs across all disease areas and conditions, using an overview of systematic reviews. The second study investigated the possibility of using factor analysis techniques to identify bolt-on dimensions. The third study explored whether it is possible to select between bolt-ons using their ability to predict differences in HRQoL. The fourth study examined whether it is possible to select between bolt-ons using preferences elicited from pairwise choices over health states. A number of important findings were made. First, GPBMs appear generally valid and responsive across many disease areas, but the quality, nature and breath of evidence makes difficult to draw definitive conclusions. Second, factor analysis techniques can be used to identify bolt-on dimensions. Exploratory and confirmatory factor analysis need to be used in conjunction. Third, bolt-ons differ in their ability to predict differences in HRQoL and for this reason they might be selected based on this information. Fourth, bolt-ons differ in terms of their impact on preferences and for this reason they might be selected based on this information. Overall, a key contribution of this thesis is to systematically examine methods for identifying and selecting bolt-ons for generic preference based measures.

Abstract:
Much previous experimentation related to wood structures has employed monotonic loading to replicate static situations. However, instances of natural hazards have raised interest in the response of structural connections to dynamic loads. This increased interest led the Consortium of Universities for Research in Earthquake Engineering (CUREE) to develop a testing protocol for reverse-cyclic loading, which involves cycling loads through zero in order to test specimens in both tension and compression. With the CUREE testing protocol in place, recent research has been devoted to understanding the effects of reverse-cyclic loading on multiple-fastener connections. Experimentation by Heine (2001), Anderson (2002), Billings (2004) and others contributed to a better understanding of bolted connection behavior under reverse-cyclic loading. However, some questions remained. Billings was unable to consistently produce yield modes III and IV, meaning that her suggested bolt spacing of seven times the bolt diameter (7D) could not be applied to connections subject to these yield modes without further testing. In addition, the work of Anderson and Billings raised questions regarding the proper measurement of bending yield strength in bolts and the relationship between the bending yield strength and the tensile yield strength. These topics are each addressed by this project and thesis report. Results of the connection testing presented in this report can be used in conjunction with the work of Anderson and Billings to critically evaluate the 4D between-bolt spacing recommended by the National Design Specification (NDS) for Wood Construction (AF&PA, 2001). Results of the bolt testing provide a supplement to the search for a reliable method for the measurement of bending yield strength in bolts.

Abstract:
Tumbling mills describe a class of mechanical systems defined by a cylindrical chamber filled with balls and/or rocks that rotate around their own longitudinal axis. Due to the action of charges, the lifters/liners wear significantly and their shape will be changed which will influence the efficiency of the mill. Liner bolts are the mill components which connect the mill interior with the exterior environment. With this property, bolts have been paid more and more attention. The first part of the thesis covers the structural analysis of the lifter/liner bolts, and the possibility for on-line charge motion measurement with the aid of bolts is discussed by comparing the strain distributions at the bolt areas where the bolts occupy different mill circumferential positions. In order to measure the lifter/liner wear, a real-time, on-line wear sensor was developed by the Comminution Dynamics Laboratory. However, the positioning of the sensor/sensors affects the strength of the mill is unknown. The second part of the project provides detailed research on this issue by FEA analysis so as to provide a basis for the practical application of this kind of sensors. Finally, during the grinding process of tumbling mills, some mills can vibrate greatly at some ranges of mill rotating speeds and as a result the mills cannot work properly because of this vibration or resonance. With six different mill models, the final part of the thesis investigates the mill natural frequencies and their modes by FEA and furthermore, explores the effect of mill diameter, length on these frequencies and modes.

Abstract:
The industry is moving towards a higher degree of automation and connectivity, where previously manual operations are being adapted for interconnected industrial robots. This thesis focuses specifically on the automation of tightening applications with pre-tightened bolts and collaborative robots. The use of 3D computer vision is investigated for direct localization of bolts, to allow for flexible assembly solutions. A localization algorithm based on 3D data is developed with the intention to create a lightweight software to be run on edge devices. A restrictive use of deep learning classification is therefore included, to enable product flexibility while minimizing the computational load. The cloud-to-edge and cluster-to-edge trade-offs for the chosen application are investigated to identify smart offloading possibilities to cloud or cluster resources. To reduce operational delay, image partitioning to sub-image processing is also evaluated, to more quickly start the operation with a first coordinate and to enable processing in parallel with robot movement. Four different hardware architectures are tested, consisting of two different Single Board Computers (SBC), a cluster of SBCs and a high-end computer as an emulated local cloud solution. All systems but the cluster is seen to perform without operational delay for the application. The optimal hardware architecture is therefore found to be a consumer grade SBC, being optimized on energy efficiency, cost and size. If only the variance in communication time can be minimized, the cluster shows potential to reduce the total calculation time without causing an operational delay. Smart offloading to deep learning optimized cloud resources or a cluster of interconnected robot stations is found to enable increasing complexity and robustness of the algorithm. The SBC is also found to be able to switch between an edge and a cluster setup, to either optimize on the time to start the operation or the total calculation time. This offers a high flexibility in industrial settings, where product changes can be handled without the need for a change in visual processing hardware, further enabling its integration in factory devices.
Industrin rör sig mot en högre grad av automatisering och uppkoppling, där tidigare manuella operationer anpassas för sammankopplade industriella robotar. Denna masteruppsats fokuserar specifikt på automatiseringen av åtdragningsapplikationer med förmonterade bultar och kollaborativa robotar. Användningen av 3D-datorseende undersöks för direkt lokalisering av bultar, för att möjliggöra flexibla monteringslösningar. En lokaliseringsalgoritm baserad på 3Ddata utvecklas med intentionen att skapa en lätt mjukvara för att köras på Edge-enheter. En restriktiv användning av djupinlärningsklassificering är därmed inkluderad, för att möjliggöra produktflexibilitet tillsammans med en minimering av den behövda beräkningskraften. Avvägningarna mellan edge- och moln- eller klusterberäkning för den valda applikationen undersöks för att identifiera smarta avlastningsmöjligheter till moln- eller klusterresurser. För att minska operationell fördröjning utvärderas även bildpartitionering, för att snabbare kunna starta operationen med en första koordinat och möjliggöra beräkningar parallellt med robotrörelser. Fyra olika hårdvaruarkitekturer testas, bestående av två olika enkortsdatorer, ett kluster av enkortsdatorer och en marknadsledande dator som en efterliknad lokal molnlösning. Alla system utom klustret visar sig prestera utan operationell fördröjning för applikationen. Den optimala hårdvaruarkitekturen visar sig därmed vara en konsumentklassad enkortsdator, optimerad på energieffektivitet, kostnad och storlek. Om endast variansen i kommunikationstid kan minskas visar klustret potential för att kunna reducera den totala beräkningstiden utan att skapa operationell fördröjning. Smart avlastning till djupinlärningsoptimerade molnresurser eller kluster av sammankopplade robotstationer visar sig möjliggöra ökad komplexitet och tillförlitlighet av algoritmen. Enkortsdatorn visar sig även kunna växla mellan en edge- och en klusterkonfiguration, för att antingen optimera för tiden att starta operationen eller för den totala beräkningstiden. Detta medför en hög flexibilitet i industriella sammanhang, där produktändringar kan hanteras utan behovet av hårdvaruförändringar för visuella beräkningar, vilket ytterligare möjliggör dess integrering i fabriksenheter.

Abstract:
AbstractDesigned for aeronautical and automotive applications, the split sleeve cold expansion process is used to improve the fatigue life of bolted metallic parts. Although its application has been well tested on aluminum assemblies, hard metal applications are still being studied. This paper presents experimental results of double bolt joint assemblies under double shear fatigue tests after stacked split sleeve cold expansion. The behaviors of two sizes of assemblies with different degrees of expansion are investigated. S-N curves are the main indicators of this study but thermal aspects are also investigated to observe fretting in the specimens as bolts are preloaded. Bolt tension is a major parameter in assembly regarding fatigue life. Interference between those two phenomena is at the heart of this paper. The first results show that stacked cold expansion has a negative effect on mechanical performances, as it deteriorates the fatigue life of the assembly. However, an examination of these results provides a coherent explanation for the loss of performance that occurs.

Full text
Abstract:
Coated bolting has been widely used on flanged joints of pressure vessels and piping whenever there is a potential for atmospheric corrosion. The applied bolt coating has to be dimensionally accommodated, typically by over tapping the nut or less frequently, under sizing the bolt threads. A recently published technical paper by MacMoy, Ian [7], alleged that this practice is not in compliance with relevant industry standards and potentially compromises the sealing integrity of the flange joint. MacMoy’s paper recommended that any coating that requires over tapping in order to apply a coating’s optimal thickness should be avoided. In this paper, the authors investigated relevant industry practices, and performed proof testing of some sample bolt sizes. The outcome of this investigation and the details and results of the proof-testing are shared in this paper.

Full text
Abstract:
The U.S. Army Corps of Engineers (USACE) currently operates and maintains approximately 193 commercially active lock sites with 239 locks and dams spanning nearly 12,000 miles. These networks of water channels are used to transport 600 million tons of domestic cargo, generating $405 billion in revenue annually. Nearly 60% of these structures in operation are over 50 years old and have reached design life. A failure of the miter gates could result in a major negative impact on the economy and on the ability to maintain flood control. Administrators need recommendations to better prioritize maintenance and repair of the USACE miter gates. This work investigated the influence of miter gate’s quoin block degradation on load transfer to the pintle and/or pintle connections. Results of finite element analysis are reported for the quoin block degradation simulated levels of 0%, 25%, 50%, and 75%. The parametric study shows the overstressed regions are the pintle neck and bolt-hole regions. To improve pintle designs so they may better mitigate detrimental environmental based deterioration effects, this work recommends (1) increasing the thickness of the bolt-hole connection region and (2) adding ribbing reinforcement around the neck area of the pintle.

NUMERICAL STUDY ON SHEAR BEHAVIOUR OF ENHANCED C-CHANNELS IN STEEL-UHPC-STEEL SANDWICH STRUCTURES. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.4.

Full text
Abstract:
This paper firstly developed a three-dimensional (3D) finite element model (FEM) for enhanced C-channels (ECs) in steel-UHPC-steel sandwich structures (SUSSSs). The FEM was validated by 12 push-out tests on ECs with UHPC. With the validated FEM, this paper performed in-depth parametric studies on shear behaviours of ECs with ultra-high performance concrete (UHPC). These investigated parameters included bolt-hole gap (a), grade (M) and diameter (d) of bolt, core strength (fc), length of C-channel (Lc), and prestressing force ratio on bolt (ρ) in ECs. Under shear forces, the ECs in UHPC exhibited successive fractures of bolts and C-channels. Increasing the bolt-hole gap within 0-2 mm has no harm on the ultimate shear resistance, but greatly improves the slip capacity of ECs. Increasing grade and diameter of bolts improves the shear resistance and ductility of ECs through increasing the PB/PC (shear strength of bolt to that of C-channel) ratio. Increasing the core strength increased the shear resistance, but reduced the ductility of ECs due to the reduced PB/PC ratio. The ECs with Lc value of 50 mm offer the best ductility. Prestressing force acting on the bolts reduced the shear strength and ductility of ECs with UHPC. Analytical models were proposed to estimate the ultimate shear resistance and shear-slip behaviours of ECs with UHPC. The extensive validations of these models against 12 tests and 31 FEM analysis cases proved their reasonable evaluations on shear behaviours of ECs with UHPC.

STUDY ON THE STATIC BEHAVIOR OF COLD-FORMED STEEL FABRICATED BEAM-COLUMN JOINT. The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.310.

Full text
Abstract:
This paper presents a new built-up beam-column joint with a spacer employed between channel sections under monotonic loading to study its static behavior. A validated finite element model was used to simulate the cold-formed steel (CFS) joint's moment-rotation behavior and failure mode by utilizing ABAQUS. It accounts for both material and geometrical nonlinearity. The model was further adopted to investigate the influence of bolt arrangement, spacing of intermediate connecting plates, diaphragms and various beam-column stiffness ratios on the joint behavior. The results indicate that the bolt arrangement and spacing of intermediate connecting plates have little influence on the joint performance. The internal vertical diaphragm can be adopted for the built-up beam-column joint, and diaphragm thickness should not be less than spacer thickness. The critical beam-to-column stiffness ratio is determined to be 0.38.

EXPERIMENTS ON BOLTED CONNECTIONS IN COLD-ROLLED ALUMINIUM PORTAL FRAMES. The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.241.

Full text
Abstract:
The use of portal frame systems composed of cold-rolled aluminium profiles is likely to be a new structural solution in corrosive environments. In such structural systems, stainless steel bolts are commonly used as connectors to fasten various aluminium components in the full-scale systems. In these connections, the point fasteners may experience either shear force, torque and/or a combination of both, leading to complex behaviours of the connections. While the failure may occur at a bolt, the other structural components are still in the elastic state. Hence, investigation into the load-deformation responses of bolt connectors is essential to further understand the complexity of bolted connections in the portal frame systems. In this study, experiments on different configurations of bolted connections subjected to shear force and/or torque were carried out at the University of Sydney to investigate the behaviour and to provide the load-deformation characteristics of the bolted connections

EFFICIENCY OF DIFFERENT CONNECTIONS ON THE BEHAVIOUR OF COLD-FORMED SINGLE-ANGLE STEEL MEMBERS CONNECTED THROUGH ONE LEGUNDER AXIAL LOADING. The Hong Kong Institute of Steel Construction, September 2022. http://dx.doi.org/10.18057/ijasc.2022.18.3.10.

Full text
Abstract:
A detailed experimental program was performed using 36 cold-formed steel (CFS) single-angle column members attached by one leg was investigated subjected to axial compression loads. The key purpose of this research is to investigate the effect of slenderness ratio and different connection types on the load-carrying capacity of CFS angle sections under axial compression. The parameters investigated via the test program includes (a) angle sections with and without lipped profile, (b) sectional thicknesses (2 mm and 3mm), (c) slenderness ratios (λ = 20, 50, 80) from short to slender columns, and (d) type of connections i.e. two-bolt, three-bolt and welded connections. Results shown that the angle sections had a significant reduction in the load-carrying capacity when the slenderness ratio was increased from 20 to 80. Moreover, the mode of failure for short columns was changed from local buckling mode to combined local and flexural buckling for intermediate columns (λ = 50) and torsional-flexural buckling mode for long columns (λ = 80). Also, a detailed analytical study was carried out comparing the predictability of existing equations from different standards for angle sections under axial compression.

A SIMPLE METHOD FOR A RELIABLE MODELLING OF THE NONLINEAR BEHAVIOUR OF BOLTED CONNECTIONS IN STEEL LATTICE TOWERS. The Hong Kong Institute of Steel Construction, March 2022. http://dx.doi.org/10.18057/ijasc.2022.18.1.6.

Full text
Abstract:
The behaviour of bolted connections in steel lattice transmission line towers affects their load-bearing capacity and failure mode. Bolted connections are commonly modelled as pinned or fixed joints, but their behaviour lies between these two extremes and evolves in a nonlinear manner. Accordingly, an accurate finite element modelling of the structural response of complete steel lattice towers requires the consideration of various nonlinear phenomena involved in bolted connexions, such as bolt slippage. In this study, a practical method is proposed for the modelling of the nonlinear response of steel lattice tower connections involving one or multiple bolts. First, the local load-deformation behaviour of single-bolt lap connections is evaluated analytically depending on various geometric and material parameters and construction details. Then, the predicted nonlinear behaviour for a given configuration serves as an input to a 2D/3D numerical model of the entire assembly of plates in which the bolted joints are represented as discrete elements. For comparison purposes, an extensive experimental study comprising forty-four tests were conducted on steel plates assembled with one or two bolts. This approach is also extended to simulate the behaviour of assemblies including four bolts and the obtained results are checked against experimental datasets from the literature. The obtained results show that the proposed method can predict accurately the response of a variety of multi-bolt connections. A potential application of the strategy developed in this paper could be in the numerical modelling of full-scale steel lattice towers, particularly for a reliable estimation of the displacements.
