型钢-高强混凝土剪力墙抗震性能试验及数值模拟分析
Seismic Performance Test and Numerical Simulation of Steel Reinforced High-Strength Concrete Shear Walls
采用低周反复加载试验研究了型钢-高强混凝土剪力墙在高轴压比下的抗震性能。利用ABAQUS子程序UMAT接口对混凝土和钢材本构模型进行二次开发,建立了墙体试件的数值模型。基于试验验证后的数值模型完成了型钢-高强混凝土剪力墙变参数分析。试验结果表明型钢-高强混凝土剪力墙在高轴压比下具有较好的变形以及耗能性能。建立的数值模型可准确地模拟墙体试件的滞回特性和抗震性能。变参数分析结果表明在保证墙体滞回性能前提下,提高混凝土强度(C60→C80)可有效降低墙体配钢率(约66.7%);提高墙体的轴压比(0.4→0.6),墙体的变形性能降低(极限位移角2.96%→4.70%),墙体峰值点后承载力显著下降;提高墙体的配钢率(2%→10%),墙体的承载力略有提升,对墙体的变形性能影响较小。
The seismic performance of steel high-strength concrete shear walls (SHCWs) under high axial compression ratio is studied by cyclic loading test. The UMAT subroutine of ABAQUS was used to develop the constitutive model of concrete and steel, and the numerical model of each wall specimen is established. Parameter analysis was conducted based on the finite element models verified by experiments. The results show that the SHCWs has good deformation and energy dissipation performance under high axial compression ratio. The numerical model can accurately predict the pinch effect and strength decline of the hysteresis curves. The simulated and experimental hysteresis curves have similar loading and unloading stiffness, bearing capacity, ultimate displacement and energy consumption. The parametric analysis shows that the steel ratio can be effectively reduced (approximately 66.7%) by increasing the concrete strength (C60→C80) under the premise of ensuring the hysteretic performance of the walls. By increasing the axial compression ratios (0.4→0.6), the deformation performance of the SHCWs is significantly reduced (ulitimate drift ratios 2.96%→4.70%), and the post-peak strength decrease of the walls is accelerated. By increasing the steel ratio of the wall (2%→10%), the increase of bearing capacity of the wall is limited, and the deformation performance of the wall is little affected.
