摘　　要：为解决剪力墙结构混凝土处理中采用分期置换法剔除原墙体对结构的影响问题,采用有限元分析的方法,研究不同开洞尺寸对结构的影响.结果表明:不同开洞尺寸会对结构产生不同程度的变形、裂缝等影响;将开洞对结构造成的影响与实际施工时条件影响综合考虑,得出最佳开洞尺寸及开洞间距,实现置换混凝土墙体的优化设计.To solve the problem of the influence of stage replacing method to remove wall on structure in treatment concrete of shear wall structure, this paper studied the effects of different hole size on the structure by using the finite element method. The results show that different hole size will have an impact on different degree of deformation and crack on the structure. Considering the effects of openings on the structure and the actual construction conditions, the best hole size and hole spacing are obtained, which optimized the design of replacement of the concrete wall.
