Based on the quasi-static test of single-layer, two-bay RC frame model, using DIANA finite element program, a finite element Macro-model of masonry-infilled frame structure was established, and nonlinear finite element analysis of frame structures filled with different masonry materials was conducted. As a result of the existence of infill walls, the failure modes of frame structure have been changed, and which is easy to cause shear failure at the top of frame columns. If masonry materials of infill walls are different, the effects of infill panels on frame structures will be different. Comparative analysis shows that the influence of clay bricks is the largest, followed by autoclaved bricks’ influence, while aerated concrete blocks’ influence is the smallest. Therefore, to avoid the associated failure mechanism caused by infill walls, lightweight masonry materials are suggested to be used in actual engineering.

Reinforced Concrete Frame Structure

Basing on the finite element analysis software, the emergence of crack under the effect of gradual changed temperature load and the change of stress which are in the condition of super reinforced concrete frame structure are analyzed from the linear and nonlinear numeral simulation. The simulation shows that the structure component under the normal condition is cracked and turn into the nonlinear condition and the steel bars still works under the elastic stage. Meanwhile the actual stage which is reflected by the elastic-plastic analysis of the internal force and deformation is compared by the results which are obtained by the actual project observed results and the calculation of the simplified model. So the distribution of the stress which is caused by the structure temperature reduction is greatly evaluated by the usage of the cracking model which is nonlinear finite element and also plays an important role in the engineering project and practice.

The building moving has more than 100 years’ history. In the building moving, the design of the underpinning joints is one of the key problems. As to the frame structure, the most widely used method is the double beam underpinning system. Our research group has conduct 16 underpinning joints tests considering the different influential factors to study the mechanical performance of it. This paper first introduces the experiment briefly. And then make finite element analysis on the mechanical behavior of the column underpinning joints using the software ABAQUS as the platform. In the finite element analysis, the solid element is adopted and the master-slave contact surface is used to simulate the interaction between the column and the underpinning beams. The results show that the failure of the moving-beam is ahead of the coupling-beam and the bending-shear failure occurred in the moving-beam. As to the interface between the column and the beam, the lower part of the contact failed and the gaps can be seen. From the analysis results, the contact stress on the column is not uniformly distributed and larger in the upper part of the contact surface which is accord to the test results.

This thesis studies deeply the crack development characteristics, failure pattern, hysteresis curve and the displacement ductility of unbonded precast reinforced concrete frame, by analyzing one unbonded precast reinforced concrete frame under low reversed cyclic load test. We build a model using finite element analysis software to the test piece model analysis, the analysis result agree well with the experimental results. So we build finite element analysis models with different design parameters to analysis the impaction for seismic performance. Numerical analysis results can provide a scientific reference for the unbonded precast frame structure design.

The paper describes the creation of the arched frame structures made of brittle material. Pasta were chosen as the base material. Their basic geometrical and mechanical characteristics were evaluated. Finite element analysis of the pasta frame structure was made in SCAD and ANSYS. The internal force factors arose in the structure were compared. Its actual carrying capacity was determined in virtue of the structural solidity and material`s experimental evidence. Also the features of optimized structure design were found, the assembly process was described, the test results of the construction were presented. The comparison of the results of finite element modeling and actual laboratory tests was done.

In the paper, the sandy pebble soil which was most massively distributed in Sichuan was used as foundation. The finite element model of mega frame structure including the superstructure, raft foundation and the sandy pebble groundwork was built by applying the finite element analysis software ANSYS. The response of the mega frame structures under dynamic load was analyzed to study the mechanical properties, deformational properties and the interaction between mega frame structures and the sandy pebble soil. At last, in the same structural style and same foundation soil, the dynamic behaviors of such structure which take no account of the interaction between mega frame structures and the sandy pebble soil was compared with structure which took account of the interaction. The research in the paper could provide certain reference value for the future engineering.

Angle Connection

There is wide use of beam-column joint with gusset plate angle connection in engineering, however, the mechanical properties of these joints are still lack of complete theoretical and experimental research. This kind of joint is often simplified as an articulated connection or other types of connections in the design. In this paper, experimental study and finite element analysis are carried out to study the flexural behavior of the beam-column joint with gusset plate angle connection. The finite element analysis is used to analyze the differences between the beam-column joint with gusset plate and other joints. The moments-rotation curves and failure modes of the three kinds of beam-column joints were obtained by the static test which were carried out. A more reasonable design of beam-column joint with angle plate of gusset plate is put forward through the research of this paper: the deformation of the column flange is restricted after adding the stiffener, which can avoid the premature yield of the column flange and making the joint have good energy dissipation capacity.

Space Frame Structure

Space frames are usually used to enhance the structural strength of a vehicle while reducing its overall weight. Impact loading is a critical factor when assessing the functionality of these frames. In order to properly design the space frame structure, it is important to predict the shocks moving through the members of the space frame. While performance of space frame structures under static loads in well-understood, research on space frame structures subjected to impact loading is minimal. In this research, a lab-scale space frame structure, comprising of hollow square members that are connected together through bolted joints which allow for quick assembly/disassembly of a particular section, is manufactured. Non-destructive impact tests are carried out on this space frame structure and the resulting acceleration signals at various locations are recorded. A finite element (FE) model of the lab-scale structure is created and simulated for the experimental impact loads. Acceleration signals from the FE model are compared with the experimental data. The natural frequencies of the structure are also compared with the results of the FE model. The results show a good match between the model and the experimental setup.

Masonry structure, the number of large, wide area distribution, and earthquake damage survey, masonry structure severely damaged. In this paper, using the finite element tool ABAQUS, combined with an equivalent volume element simulation technology, the establishment of spatial finite element model to study the loading height of the brick wall failure modes and effects of seismic performance issues in depth analysis of its constant vertical pressure, different loading height seismic performance and failure modes under. The results show that: the greater the load height, the wall more prone to bending failure, otherwise prone to shear failure; loading height bigger, better ductility of the wall, the ultimate bearing capacity is smaller.
