摘　　要：传统现浇钢筋混凝土剪力墙结构具有自重大、刚度大、抗震作用大、延性差以及保温隔热性能低等建筑节能性能差等等诸多的缺点.随着建筑业的迅猛发展,大量的试验研究和有限元计算分析表明:钢筋混凝土空心剪力墙刚度小,延性好,是一种很好的节能性的延性剪力墙结构,更适用于高层建筑.本文主要利用ANSYS的结构拓扑优化模块对钢筋混凝土空心剪力墙的拓扑形状进行结构优化设计,建立以总体积为目标函数,以应力和变形状态变量为约束条件,以空心剪力墙孔洞的直径为优化变量的钢筋混凝土空心剪力墙的优化设计模型,并采用零阶方法进行优化设计和计算.Traditional cast-in-situ reinforced concrete shear wall has the shortcomings of heavy weight,stiffness,anti-seismic effect,short of ductility and low heat preservation and thermal insulation.With the rapid development of construction industry,a lot of experimental research and finite element analysis showed that： reinforced concrete hollow shear wall is weak in stiffness and good in ductility and it is a very good energy conservation structure and can be applied in high-rise buildings.This paper mainly made use of ANSYS structural tropical optimization toward reinforced concrete hollow shear wall and established the reinforced concrete hollow shear wall based on total volume as target function,stress and deformation as restricted element,diameter of hollow shear wall as optimization variable quantity,and adopted zero-order to optimize design and calculation.
