摘要
采用PKPM系列软件和有限元程序SAP2000,分析了钢框架-剪力墙和交错桁架-剪力墙两种结构方案的抗震、抗风性能,以及在满足设计规范前提下的结构用钢量.对比设计结果显示,交错桁架-剪力墙比钢框架-剪力墙用钢量低,纵向框架结构形式对交错桁架的用钢量有一定影响,设计时宜采用剪力墙或支撑体系增强纵向框架刚度.
PKPM＇s series software and finite-element program SAP2000, the behavior of aseismic and resistance to wind of steel frame-shear wall structure with staggered truss - shear wall structure are adopted in analyzing the steel material quantity of each structure scheme under satisfying design code. The contrastie design results show that the steel consumption of staggered truss-shear wall structure is lower than that of the steel frame-shear wall structure, and the longitudinal frame structure form may affect the steel consumption to the staggered truss. The designer is advised to adopt shear wall or bracing system to strengthen longitudinal frame stiffness.
