This paper intends to investigate the seismic performance of double steel plate concrete combined shear walls with different axial pressure ratios in different temperature environments.The study is formed by designing 12 shear walls with the control parameters of temperatures(40,20,-40℃)and the axial pressure ratios(n=0.3,0.4,0.5 and 0.6);verifying the accuracy of the finite element results by comparing the double steel plate combined shear wall test by using ABAQUS;comparing and analyzing the bearing capacities,plastic degeneration capacities,energy consumption capacities and ductilities of the 12 shear walls;and exploring the seismic performance variation rule of the test-piece with the axial pressure ratio under the representative temperature environment.The results show that under the same temperature environment,with the increase of the axial pressure ratio,the bearing capacity of the shear wall increases,and the ductility decreases.The effect of the axial pressure ratio on the stiffness degrada-tion is not obvious.In the environment of 20℃,the ductility of the shear wall is better than that in 40℃and-40℃environments;and in the environment of-40℃,the bearing capacity of the shear wall is higher than that of 40 and 20℃,under different temperature environments.
