［摘要］高层住宅的结构选型对其用钢量有直接影响。25～33层(高度接近100m)的高层住宅，采用剪力墙结构体系比采用框架-剪力墙结构体系的用钢量低，且抗震性能比后者的更好。应对剪力墙进行合理布置及优化设计，优化设计后，结构安全度不应降低，剪力墙具有更好的延性和抗震耗能能力，且用钢量较低。采用相关的设计实例进行说明，对高层住宅设计具有广泛的适用性和现实指导意义。

Abstract:The structural system selection of the high-rise residential building will directly influence the consumption per square meter of reinforcement. The high-rise residential building of 25～33 layers(about 100m in height)，which the shear wall structural system is applied to, will more easily obtain lower consumption per square meter of reinforcement than the building which the frame-shear wall structural system is applied to, while the shear wall structures show better earthquake-resistant behaviors than the frame-shear wall stru
