The understanding and assessment of accidental crash scenarios on reinforced concrete structures is of high interest for safety issues. Although experimental research on this topic has already a long and successful history, there are many issues waiting to be solved as far as numerical simulations are concerned. In this article some particularities of the Abaqus Concrete Damaged Plasticity (CDP) model are investigated with the purpose of using efficiently the CDP model in impact loaded reinforced concrete structure simulations. In particular, the sensitivity of the simulation response with respect to model parameters and element size is studied. The simulation response is compared to measurements from benchmark impact tests on reinforced concrete plates.

Streszczenie:

The mechanics analysis of integral building structure needs the accurate ABAQUS finite element analysis, but due to the ABAQUS function limits the building structure modeling is a great workload and how to model an integral structure more quickly and efficiently become a difficult problem. In order to reduce the workloads in the ABAQUS analysis, the new ABAQUS standard layer assembly modeling approach was proposed. Firstly, according to the data structure of the ABAQUS software’s INP file, the program computational algorithm was proposed. And by a Python self-written program, the example engineering structure model was completed using this standard layer assembly approach. The usage of this new ABAQUS modeling approach makes the modeling more easy and efficient. After that, by comparing the ABAQUS standard layer assembly model calculation results with the results calculated by another finite element software, it is clearly illustrated that the ABAQUS standard layer assembly modeling is more accurate and can be applied in the structure analysis.

The damage evolution equation of RPC is established based on 2-parameter Weibull distribution. The constitutive relation of RPC is then calculated based on the damage evolution equation. The constitutive model of RPC is optimized by comparing experimental constitutive curve to models corresponding to different threshold strain. Based on the definition of damage index in ABAQUS, the damaged evolution equation in ABAQUS is recalculated based on the optimized constitutive relation. the concrete damaged plasticity model in ABAQUS is obtained using the aforementioned method. And the concrete damaged plasticity model is applied to three compression member and three simply supported beams with different reinforcements. The calculated stress-strain curve and deformation of three compression member and three beams is in accordance with the deformation characteristics of experiments, which verified the effectiveness of the proposed concrete damaged plasticity model of RPC.

In this thesis, the dynamics of two plates overlapping and connected by three bolts are studied. The data collected in the test are used in modal analysis. The vibrational test and the modal analysis were made using an LMS system. Hammer excitation is used for the tests. The main purpose of this thesis is to study how the suspensions affect the extracted eigenfrequencies and modal dampings. In this thesis, more than 10 suspensions were examined. Another objective in this thesis work is to build an FE-model. This model is made using the software Abaqus. To improve the reliability of the FE-model, a set of reliable experimental data is used to calibrate the model. The calibrated FE-model, using the measurement data, has a dynamic behavior close to the measurement data.

Finite Element Analysis (FEA) is proposed to simulate the connection response of practical in-service conditions and test the performance of Oil Country Tubular Goods (OCTG) premium threaded connections. A plug-in is developed in Abaqus/CAE for creating the 360-degree full 3D parametric finite element model with helical threads as an effective design and analysis tool. All size, position and material data of the model are parameterized. The premium connection plug-in accepts input from the Graphical User Interface (GUI) for further modification. Each premium connection component is programed as a collection of single-purpose independent functions organized as an independent module in order to allow users to modify specific function behavior conveniently. A main program is designed as an Abaqus kernel plug-in to achieve all the functions by calling these independent functions, making the plug-in flexible. Each single script file is not too long to jeopardize readability. The GUI of the plug-in is designed with proper layout arrangement and illustrations to make the plug-in user-friendly and easy to use. The premium connection FE model is used in a virtual test to validate the model against the ISO 13679 test protocol and is used to develop the seal metrics for points on the ISO 13679 sealability envelope. The plug-in can be used to develop and evaluate the design envelope of the premium connection.

Streszczenie:

The current research analyzed the flutter response of the Stonecutters Cable-Stayed Bridge in Hong Kong, which has a twin deck configuration, under the effect of wind. The aerodynamic instability response of the bridge steel deck of the main span is mainly the focus of the current project. Initially, a complete finite element bridge model was created in ABAQUS finite element software, representing all the structural elements of the Stonecutters Cable-Stayed Bridge in a lumped mass bridge model. The natural frequencies and the vibration modes were validated against the data available in the literature at first. Secondly, the effect of the mean wind loading for wind speeds between 35 m/s and 211 m/s were determined. The vertical and horizontal displacements and the torsional angle at mid-span are indicated to determine the bridge performance under mean wind load. Moreover the flutter instability was modeled based on Scanlan’s theory and the response of the bridge model at several different locations along the main and the side span and the top of the tower, were determined for wind speeds of 35 m/s and higher, where this critical aerodynamic instability is expected to occur. In addition, the responses of the bridge under natural wind data were also determined by applying a wind speed recorded data to the bridge model. Finally, the critical flutter wind speed and the flutter frequency were determined by Fast Fourier Transform in MATLAB program. The flutter onset wind speed was also determined.

As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. On railway bridges, an increased trainspeed potentially leads to an increase in vibrations during passage, for which the structure may not bedesigned. It is therefore essential to know the dynamic properties of the structures used.Several studies highlight the influence of friction phenomena in sliding bearings on the dynamicproperties of bridges equipped with them. This Master Thesis is based on previous works that led tothe development of a finite element modelling the friction mechanisms that occur in these bearings.The friction occurring between a PTFE sliding plate and a steel surface is thus modelled using the Bouc-Wen model, a model for hysteresis phenomena. The finite element was developed as a Fortransubroutine, which can be integrated into the finite element calculation software Abaqus as a "userdefinedelement". It allows friction to be modelled along the longitudinal direction of the bridge onlyand can therefore only be used in two-dimensional models. The user-defined element is also based ona model that takes into account the influence of contact pressure and sliding velocity on the steel-PTFEcoefficient of friction. As several studies indicate, contact temperature can also have a significantinfluence on the value of the coefficient of friction but is not taken into account in the current model.In this project, the previously developed finite element was therefore generalized to account forfriction in both directions of the sliding plate by the means of a two-dimensional generalization of theBouc-Wen model. Based on experimental data available in scientific literature, the model forcalculating the coefficient of friction was also extended to take into account the influence of thecontact temperature. In addition, a model to update the contact temperature based on the theory ofsurface heating of semi-infinite bodies has been incorporated. Finally, this thesis presents theintegration of this updated finite element on three-dimensional models of the Banafjäl Bridge, locatedin northern Sweden. Simulations to estimate the fundamental frequencies and resonance modes ofthe structure as well as the temperature increase that can occur in a bearing during the passage of atrain were carried out on this model.

Packaging industries widely use Low-Density Polyethylene (LDPE) in manufacturing different types of containers to store the food products. They are difficult to model numerically in order to have similar experimental response. This research deals with the study of numerical material model parameters of continuum LDPE. It is carried out with the help of experiments along with the numerical simulation of LDPE. Study of stress-strain distribution at crack tip and elements close to the tip is carried out in the LDPE material with the pre-existing center crack with varying lengths. By implementing an optimization algorithm and automating the simulation with the help of python code, we obtain a set of parameters. This obtained data for the material can be used directly for numerical simulation in the future without carrying out additional experimental studies. After implementing the optimization algorithm is also validated, against the results that were close to the experimental response.

Streszczenie:

Understanding the true behaviour of impacted structures is the only way to assess their robustness under exceptional events such as vehicle collision. The primary objective of this master’s thesis was to perform a finite element parametric investigation on the influence that some parameters have in steel buildings subjected to vehicle impacts. The parameters chosen for the study, involved uncertainties in the material definition and in the load configuration of the bolts used in the impacted column end-connections. By using the Abaqus software, a finite element model of the structure has been created. The five storey steel building considered has been modelled in a simplified manner with the exception of the impacted area which, instead, has been defined in a more detailed fashion. During the simulations, different preload conditions have been used, comparing cases with and without the preload force. Regardless its variation, it has not been observed any increase in the structural resistance. On the other hand, the simulation provided interesting results for what concerns the material variations in the bolts. Although the changes have been small in magnitude, the effect on the structural response during the impact was remarkable. For all the cases considered, an increase of the material ductility, achieved by increasing the ultimate strain at failure, entailed higher resistance of the connections. Various failure modes have been observed when the material properties have been changed. Having clarified the influence of the assumptions made, the results provided helpful information in sight of future studies. Although the model still needs to be validated, the research clarified which of the parameters investigated are to be collected with more attention. Keywords: Vehicle collision, steel building, FE model, Abaqus/Explicit, parametric investigation, bolt preload, bolt material.

Streszczenie:

Glued connections are relatively new in structural timber engineering. They are expected to show high connection stiffness as well as a high connection strength compared to mechanical connections e.g. dowel‐type connections.The main aim of this thesis is to characterize the behavior of glued timber connections under pure tension by conducting experiments as well as numerical simulations. Hereby the influence of different parameters is studied such as the geometry (bond-line length and thickness) and the material properties (e.g. adhesives of highly diverse stiffness). Additionally, reference tests on a dowel-type connection are made. The purpose is to see the differences between dowelled and glued connections and to see if there are some advantages in using glued timber connections (the base geometry was chosen acc. to Eurocode 5).Finite element models were created in the software ABAQUS. The models were used to predict the connection stiffness and compare this to the experimental results. In addition, parametric studies were performed on e.g. overlapping lengths. The comparison between experiments and simulations showed good agreement.It was found that glued connections with the adhesives SikaPower-4720 and SikaFast-5215 NT (an epoxy and an acrylate, respectively) had higher stiffness than the dowel connections, whereas connections with the silicone adhesive SikaSil SG-500 had a lower stiffness. A general conclusion drawn from this work is that the glued timber connections simulated in this project should also be suitable for application to complex connections and situations involving other loading situations than pure tension.

AbstractIn the circular steel tube confined reinforced concrete (STRC) column frame structure, because there is no effective restraint of steel tube in the joints area, it becomes a relatively weak part. Therefore, this paper proposes a STRC column joints with a section of steel tube built in the joints area, and expounds the structural form of the new joints. ABAQUS finite element analysis software is used to simulate the quasi-static test of joints. On the basis of verifying the rationality and reliability of the finite element analysis method, six joints models of build-in steel tube reinforced STRC columns with different lengths are established. Based on the model skeleton curve obtained by simulation analysis, the eigenvalues of each loading stage are fitted to obtain the skeleton curve model regression equation and stiffness degradation law. The three fold restoring force model of steel tube STRC column joints with different lengths is established. The skeleton curves of restoring force model and finite element calculation results are compared and analyzed to verify the correctness of restoring force model. The results show that the restoring force model is in good agreement with the finite element analysis results. The established restoring force model can provide a reference for the elastic-plastic change and seismic analysis of build-in steel tube reinforced STRC column joints.

AbstractRectangular columns used in flat-slab structures run the risk of punching shear damage due to stress concentrations, especially when bending moments and vertical forces act together at the connections. Using the finite element analysis method, the existing experiments are numerically simulated using the 3D modeling software ABAQUS, and describe the cracking behavior of concrete using the concrete damaged plasticity model. The accuracy of the numerical simulation was calibrated by load–displacement curves and crack patterns using the experimental results. The study of the model was set up with different moment-to-shear ratios and outputs the trend of the average shear stress on the eccentric force side of the slab. The moment transfer coefficients are derived through the equation of ACI-318 and compared with the code values. A safe range of side length ratios is proposed to reduce the risk of punching shear damage from the use of rectangular columns. This provides a reference for practical design, but more experiments are needed to support the proposed recommendations.

AbstractThe development of assembly construction technology has become an inevitable way for the transformation and upgrading of China’s construction industry. However, in the development process, the grouting sleeve connection quality problem is the most prominent. In this paper, ABAQUS model is used to establish a concrete column model with grouting defects, and the influence of grouting defects on the seismic performance of concrete columns is explored: Under the condition of the same defect location and quantity, the larger the defect size, the lower the bearing capacity, the worse the ductility, the weaker the energy dissipation capacity; In the case that the number and size of defects are the same, the positive and negative directions of the hysteresis curve are symmetric when the defects are located in the direction of stress, and the energy dissipation capacity is higher than that when all the defects are located on one side of the column section.

AbstractCapital is one of the common measures to strengthen the slab-column connections. It can make the joint's load capacity increase. However, when the connection is subjected to the unbalanced bending moment, the reduction effect of the capital on the bending moment is to be studied. Nonlinear finite element analysis is performed on reinforced concrete slabs with column capital for various moment-to-shear (M/V) ratios. The effect of capital radius on the punching shear resistance of slab-column connections is investigated. The 3D finite element modeling is performed using the concrete damage plasticity model and concrete constitutive equations. The concrete damage plasticity model parameters are calibrated by the experiment results of specimens. Increasing the radius of capital can improve the bearing capacity of nodes and reduce the moment transfer effect obviously.

AbstractThis study investigates the vibration characteristics of composite timber-concrete floor systems to provide a reliable benchmark for optimizing composite floor system designs. This paper uses the numerical and analytical methods for evaluation to support more detailed study results and to build a comprehensive model for future research. Through Strand7 and ABAQUS numerical finite element analysis, geometrical layout and beam material effects on the timber-concrete composite floor are thoroughly explored. Meanwhile, the analytical results are further compared with the analytical solution based on the Dunkerley method and AISC. Then 15 kinds of timber-concrete composite floor designs are simulated and numerically tested. It was found that the dimensions of the timber beams and their composition might affect the natural frequencies of the floors. On this basis, this paper proposes future design schemes to provide reliable suggestions for further research.

For a steel catenary riser system, the touch-down point is often a concern as it can influence the structural response of the riser and its performance. Although, riser configurations can be designed to withstand wave loading, internal pressure, external pressure, and thermal loads; the design of risers taking into account the interaction between the riser and the soil, with cycles of contact and separation, still remains challenging. More specifically, when the riser contacts the seabed surface, it penetrates into the soil material. This penetration can cause suction-type behavior when the riser moves away from the surface. Further, it causes permanent deformation in the soil so the riser has to traverse additional distance prior to re-contacting the seabed surface. For formulating a robust riser design using the finite element method, accurate modeling of this nonlinear riser-soil interaction is needed. In the majority of situations, risers are modeled with beam elements. This is an efficient approach considering that a riser-pipeline system can be several thousand meters in length and using shell or brick elements for modeling such a system becomes computationally expensive. In addition, the seabed surface is often modeled as a rigid surface. The riser-soil interaction behavior is then incorporated into the finite element analysis either by defining springs at the contacting nodes or by modifying the normal contact stiffness for the interaction. However, these methods do not entirely capture the nonlinear riser-soil interaction behavior. In this paper, we discuss the modeling of the nonlinear riser-soil interaction through the use of a user subroutine that runs in conjunction with a finite element analysis using Abaqus. This subroutine is intended to provide a special contact interaction property definition between the riser and the seabed. This contact property definition focuses primarily on the normal behavior although frictional resistance is also considered. The results of the simulation and the insights gained are included.

The classical phenomenological compressible Hart-Smith model expressed in exponential-logarithmic terms of stretch invariants is compared with substantial hyperelastic models available in Abaqus. It is implemented in Abaqus Explicit using a customized user subroutine. Compressible Hart-Smith model together with selected acclaimed models available in Abaqus are evaluated under uniaxial tension, equi-biaxial extension and planar tension modes of deformations. The required material constants are determined from a simple uniaxial tension test. In order to investigate mode-independent characteristics of considered models, predictive planar tension and biaxial extension simulations are performed using the material constants derived from a uniaxial tensile test. Obtained numerical results are validated with respect to classical experimental data for natural rubber reported by Treloar.

Finite element models are increasingly being utilized in composite materials design; thus, an increase in the accuracy of the model analysis and a decrease in computational cost are of paramount importance. This study investigates the effects of a particular add-on, Helius:MCT (Firehole Technologies, Inc.), onto the Abaqus (Dassault Systèmes) software package. Unlike the stand-alone Abaqus software, Helius:MCT embodies a solver, which analyzes the composite structure by separating the fiber and matrix into constituent parts. Treating the fiber and matrix as separate, yet linked entities, allows for a more accurate depiction of the formations of stress and strain within the composite. Furthermore, Helius:MCT utilizes a method called Intelligent Discrete Softening (IDS), a feature not present within Abaqus, to increase solver robustness and convergence probability. An Abaqus finite element (FE) model of a notched, carbon-fiber panel loaded in bending was used in this study. Six different laminate combinations were tested with six variations of the Abaqus model. Three of the variations used Helius:MCT with Abaqus and three the stand-alone Abaqus package. The combinations were composed of either 20 or 40 plies with 10, 30, or 50 percent all zero ply orientations. All the FE analysis results were compared to experimental values for a plate of the exact configuration as that of the model. The most accurate results were obtained using Helius:MCT. The configuration with the greatest accuracy utilizes Helius:MCT and deviates an average of 1.7 percent from experimental values for maximum flexural strength. A single run takes an average of 7 hours to complete. Conversely, the most accurate configuration obtained without the use of Helius:MCT deviates an average of 10 percent from the experimental values and takes over 80 hours to run. Helius: MCT increases the accuracy and decreases the computational costs of the analyses of composite models in Abaqus. The improvements in analyses while using Helius: MCT may allow for a substantial savings in experimental costs and in valuable time.

Streszczenie:

As an advanced high-performance bimetallic steel, metallurgically bonded stainless-clad (SC) bimetallic steel has been increasingly used in engineering structures in recent years. Its combination use with concrete in composite structures is beneficial to not only the corrosion resistance and economy, but also to the loading capacity. However, at present, the numerical analysis model suitable for the SC bimetallic steel is still in the lack stage. In order to study the deformation and mechanical properties of concrete-filled stainless-clad bimetallic steel square tubular (CFBSST) stub columns under axial compression, two finite element (FE) models are established based on the FE software ABAQUS. The simulation results are compared and validated according to the experimental results. Finally, the advantages, disadvantages and application scope of each model are summarized to provide reference for subsequent research.

To cater engineering application needs, cold-formed steel (CFS) members often have some web openings which could influence bearing capacity of the steel beam under combined bending and shear action. This paper presents tests on 20 groups of thin-walled web-perforated lipped C-shaped CFS beams, which were conducted under single point loading mode at mid-span. Besides, detailed finite element parameter analysis on the high shear-span ratio (a/h= 1.5 ~ 4.0) specimens was conducted by ABAQUS after the model was verified, which was mainly focused on the influences of different hole depth-to-web height ratios (dh/h) and web height-to-thickness ratios (h/t) on the bearing capacity and failure modes of the beams. Based on the results of test and FEA, the mechanical behavior and failure rules of thin-walled web perforated lipped C-shaped CFS beams under combined bending and shear action were deeply studied.

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.

In order to explore the behavior of cross-shaped steel reinforced concrete (SRC) columns after fire, the heat transfer analysis model and structural analysis model were established by ABAQUS software. The simulation results of the cross-shaped column were compared with the existing test results, in the aspect of the temperature distribution, time-temperature curve, failure mode, and load-displacement relationship after fire exposure. The results show that the simulation results agree well with the experimental results. The influence of critical parameters on residual bearing capacity coefficient k was discussed, which including constant heating duration, maximum heating temperature, concrete strength, yield strength of section steel, yield strength of rebars, limb thickness, effective column length, rebar diameter, and steel content. Finally, a simplified formula was proposed to calculate the residual bearing capacity of cross-shaped SRC columns after fire.

Streszczenie:

This paper presents an investigation on seismic performance of a ring-beam connection that is used to connect reinforced gangue concrete (RGC) beam to coal-gangue concrete-filled steel tubular (GCFST) column. Two specimens, including an interior connection with two beams and an exterior connection with one beam, were designed and fabricated for experimental tests under full-reversing cyclic loads at beam ends. In addition, finite element models which corresponded to tested specimens were developed using ABAQUS to conduct numerical simulations of the composite connection subjected to the combined axial and cyclic loads. The feasibility of the developed model to predict failure modes and load-deformation response of the connection was validated by comparing with test results. The response of the ring-beam connection to cyclic loads was examined with respects to the load-bearing capacity, deformation resistance, stiffness and strength degradation, ability to dissipate energy in a seismic event, and ductility. With numerical models, parametric analysis was completed to evaluate the influences of material and structural parameters on connection resistance against cyclic loads. Based on the results of parametric studies, a restoring force model of skeleton curve for the ring-beam connection was developed in terms of ultimate capacity and corresponding deformation. The results provided practical suggestions for the application of ring-beam connection to GCFST column in the projects.

NUMERICAL ANALYSIS AND EVALUATION OF EFFECTIVE SLAB WIDTH OF COMPOSITE CONTINUOUS BEAMS WITH SEMI-RIGID JOINT. The Hong Kong Institute of Steel Construction, grudzień 2021. http://dx.doi.org/10.18057/ijasc.2021.17.4.1.

Streszczenie:

The characterization of the structural behavior of composite beams is directly affected by the determination of the effective slab width. Various codes propose their own definitions of the effective width based on the beam span and the slab width parameters. However, the evaluation of the effective width may be influenced by other parameters. The aim of this work is to determine the most important factors affecting effective width for continuous composite beams with semi-rigid joints using numerical simulations. A three-dimensional finite element model of a composite continuous beam using explicit-solver available in ABAQUS is developed. The proposed model is validated through comparisons to available experimental results. A modified model is proposed based on the so-validated model to study the influence of the composite beam-column joint stiffness on the effective width. Then, both numerical models are used to perform an extensive parametric study to investigate the influence of various parameters on the estimation of the effective slab width. The influence of slab width, the shear connection degree, and composite joint stiffness are particularly analyzed to find out the most important parameters influencing the effective width so that simplified equations for the calculation of the effective slab width are proposed.
