加拿大设计规范没有给出钢护套冷弯型钢(CFS)框架剪力墙的设计方法。对各种类型的单肢剪力墙进行基于位移的荷载试验,研究它们的性能,并建立了综合信息数据库。剪力墙承受水平荷载以及水平和重力相结合的荷载,各剪力墙的钢护套厚度、螺纹紧固件细部构造、框架层数、纵横比以及加固措施各不相同。框架单元无法阻止翼缘螺栓受拉破坏时,钢护套的连接形式直接影响着荷载作用下构件的性能。对试验过程和试验结果进行了详细介绍。
Canadian Design Code does not give the design method of shear wall of CFS frame. Displacement-based load tests are conducted on various types of single-limb shear walls, their performance is investigated, and a comprehensive information database is established. Shear walls are subjected to horizontal loads and combinations of horizontal and gravitational loads. The thickness of the steel sheath of each shear wall, the details of the threaded fasteners, the number of frame layers, the aspect ratio, and the reinforcement measures vary. When the frame unit can not prevent the flange bolt from being damaged, the connection form of the steel sheath directly affects the performance of the component under the load. The test process and test results were described in detail.
