Based on experiment of two mixed frame with SRC columns and steel beam under low-reversed cyclic loading, hysteresis behavior, ductility, energy dissipation are studied. The test results show that the mixed frame with SRC columns has better seismic performance. The nonlinear finite element analysis on the seismic behavior of the frame specimen was conducted using Openness developed by the Pacific Earthquake Engineering Research (PEER) Center. The calculated results are much coincided with the tested results.

Force Mechanism

Two different kinds of steel-encased concrete composite beam connected concrete filled low-cycle reversed loading. The test results indicate that the two joints both have higher bearing capacity, better ductility performance and seismic behavior. In order to theoretically analyze the joints force mechanism, the nonlinear finite element analysis (FEM) of the above two joints has been conducted by using the ANSYS program. According to the results of FEM, the hysteretic curves and the skeleton curves are deduced. And from the contrast between the test results and the finite element results on energy dissipation capacity and ductility, it indicates that the theoretical results and the experimental results are basically coincident. But the errors of them are occurred due to the difference of material constitutive model. The precision of the nonlinear finite element analysis of reinforced concrete is depending on the constitutive relation of concrete to a large extent.

Modeling Process

In this paper, in order to understand fully the development of failure mechanism, bearing capacity and seismic performance of the steel H-beams and composite concrete filled steel tubular (CFST) column joints strengthened by outside strengthening ring, in the space zone the effects of changing the axial compression ratio is investigated. A 3D joint finite element model is built up by finite element software ABAQUS, the elastic-plastic finite element analysis is carried through numerical modeling process. The analysis results showed that low axial compression ratio has a little influence on the bearing capacity; with the increase of axial pressure the bearing capacity will decrease in a high axial compression ratio, moreover the failure pattern of joint changes from beam end to column end. The ductility of the specimens is decreased by raising axial compression ratio.

The article analysis the seismic behaviors of circular steel tube composite column filled with steel reinforced concrete by the large finite element analysis software ABAQUS, adopted the load-displacement method and aimed at studying the mechanical properties of circular steel tube composite columns filled with steel reinforced concrete under horizontal low-cyclic loading, considering the degree of ductility, capacity of energy dissipation by the steel ratio and axial compression ratio. Under different axial compression ratios and steel ratios, the hysteresis curves and skeleton curves are carried out. Along with the increase of steel ratio, the deformation ability and ultimate bearing capacity are raised, but with the increase of axial compression ratio, the deformation ability becomes worse.

With the help of large general finite element analysis software ANSYS, under different parameters, this paper will have a finite element analysis of bearing capacity on circular steel tube compile short column filled with steel reinforced concrete(STCSRC).In the paper,it uses separate models to calculate and analyze.Considering the nonlinear constitutive relation of steel and concrete and determining the type of unit,it is shown that stress distribution and load-displacement curve of specimen under the effect of different parameters.According to the curve and data,analysis results of bearing capacity of specimen have been shown that bearing capacity of STCSRC will increase with concrete strength increasing and it also will increase with steel rate increasing under axial load.Because of core concrete working together with steel tube and angle steel,it can significantly improve the bearing capacity of composite columns, slow down and inhibit shearing inclined cracks occur in the core concrete and develop,and improve the ductility of columns.

The Finite Element Analysis

To reduce the construction cost of the domestic promotion of the new prefabricated concrete shear wall structure system which is promoted in our country. To analyze the factors which can affect the load-carrying capacity and seismic performance of shear wall, including the axial compression ratio, the concrete strength, the reinforcement ratio and some other factors. Among all these factors, the axial compression ratio is the main factor influencing the seismic performance and the section ductility [1]. This paper adopts the ANSYS finite element analysis program, operating a nonlinear analysis on the performance of the precast shear wall when it is with one-way loading, studying the axial compression ratio's effect on the bearing capacity and deformability of the precast shear wall. According to the finite element analysis, when the axial compression ratio is between 0.2 to 0.4 and as it rises, the specimen's bearing capacity and stiffness will increases while deformability and ductility will decrease. Through the finite element analysis, we can provide reliable theory basis for the performance of the precast shear wall when it is with one-way loading.
