某高烈度区研发大楼需要有大空间测试区且分散分布,能布置上下贯通剪力墙位置很少,造成结构复杂,设计指标难以达到要求且构件截面过大。通过设置防屈曲支撑体系,并通过静力弹塑性推覆分析,展示了这种结构体系在高烈度区少墙框架结构中应用的优越性。屈曲支撑能使梁柱截面大大减小,层间位移和扭转满足要求;可降低总造价增加建筑使用面积。 A high-intensity area R & D building requires a large space test area and distributed, can be arranged up and down through the shear wall position is very small, resulting in complex structures, design specifications difficult to meet the requirements and component cross section is too large. The buckling brace system is set up and the static elastoplastic pushover analysis is applied to demonstrate the superiority of this system in the application of low wall structure with high seismicity. Buckling support can greatly reduce the beam column cross section, interlayer displacement and torsion to meet the requirements; can reduce the total cost to increase the building area.
