The Study Of Seismic Behavior Of Steel-reinforced High-strength Concrete Short Pier Shear Wall Based On Finite Element Software ABAQUS

In order to study the difference on seismic performance of the rectangular steel-reinforced high-strength concrete short pier shear wall whose factors are different, based on the finite element method calculation, this paper simulate the experiment of16specimens with different design parameters under low reversed cyclic loading using ABAQUS.At first, to confirm if the results of the simulation of the specimens under low reversed cyclic loading are reasonable, the paper simulated and analyzed the experiment on seismic performance of two rectangular steel-reinforced high-strength concrete short pier shear walls. The conditions of models are in accord with the test’s. Comparing the results of simulation and experimental, both of them failed in the same way. There a little difference between the test and the simulation in hysteresis curve, skeleton curve and bearing capacity. That is to say the simulation results calculated with ABAQUS are believable.This paper designed and simulated a series of orthogonal specimens which include four factors and every factor have three levels. They are in total9. It compared failure pattern, bearing capacity and seismic performance indicators of specimen and studied the effects on seismic performance made by different axial compression ratio, shear span ratio, limb high thickness ratio and distance between stirrups of specimens. In addition, it designed the four specimen with different steel distribution and three specimen whose grade of concrete are different and analyze the influence of two factors on seismic performance of the specimens. The study results show that:the axial compression ratio, shear span ratio, width-depth ratios, distribution form of steel and concrete grade make a great influence on the seismic performance of specimens. The greater the axial compression ratio is, or the smaller the shear-span ratio is, or the smaller the width-depth ratio is, or the higher concrete strength is, the poorer the seismic performance of the specimens. Compared the seismic performance of the specimens with different steel form, it can be found the seismic behavior of the solid-web specimen is best, the truss type and solid web with holes members are second, the seismic performance of reinforced concrete specimen is the worst.
