摘　　要：以某换流站高端阀厅为例,对型钢混凝土剪力墙模型进行有限元分析。研究结果表明:型钢混凝土剪力墙的受力共分为三个阶段。在弹性阶段,型钢混凝土剪力墙模型整体变形较小;塑性阶段,剪力墙端部钢筋和型钢先后发生屈服,模型整体变形增大;破坏阶段,模型混凝土开裂区域不断扩大,受压区混凝土达到极限压应力,结构发生破坏。Taking the high-end valve hall of a converter station as an example,the finite element analysis of the steel reinforced concrete shear wall model is carried out.The research results show that the force of steel reinforced concrete shear wall can be divided into three stages.In the elastic stage,the overall deformation of the reinforced concrete shear wall model is small.In the plastic stage,the end steel and the section steel yield successively,and the overall deformation of the model increases.In the failure stage,the cracking area of the model concrete continues to expand,the concrete in the compression zone reaches the ultimate compressive stress,and the structure is destroyed.
