摘  要:针对传统的剪力墙抗震特性数值模拟方法中由于试验条件多、参数复杂导致的模拟稳定性差的问题,提出建筑钢混剪力墙抗震特性数值模拟。选用Kent-Park模型模拟剪力墙的混凝土部分,采用Steel02模拟钢筋部分,并定义剪力墙截面,建立建筑钢混剪力墙有限元模型,考虑地震灾害对剪力墙的实际影响情况,确定抗震性能评估参数为承载力、刚度和延性以及耗能,设计对应的计算方式,根据计算结果衡量剪力墙抗震性能。实验结果表明:设计的建筑钢混剪力墙抗震特性数值模拟方法参数影响均衡,能量消耗控制波动值小,控制更精准,其整体稳定性得到了提高。Generally,the traditional numerical simulation method of seismic characteristics of shear wall has the poor stability caused by many test conditions and complex parameters.In this regard,this paper proposes the numerical simulation of seismic behavior of building steel-concrete shear wall.Kent park model and Steel02 were adopted to simulate the concrete part of shear wall and the reinforcement,respectively.Then the shear wall section was defined to establish the finite element model of the building steel-concrete shear wall.Combining with the influence of earthquake disaster on shear wall,the seismic performance evaluation parameters were determined as bearing capacity,stiffness,ductility and energy consumption,and the corresponding calculation method was designed.The seismic performance of shear wall was evaluated according to the calculation results.The results show that the simulation method designed in this work has balanced parameter influence,small energy consumption control fluctuation value,precise control,and improved overall stability.
