为研究如何提高装配整体式组合楼板的空间作用,以及能否取代楼板现浇面层以减轻结构质量,采用拟动力试验方法对按1/4比例缩小的两跨、3层的现浇楼盖板-框架剪力墙结构(SJ1)和在楼盖板下加X水平斜撑的装配整体式楼盖板-框架剪力墙结构(SJ2)两个模型进行了弹性比较试验。试验结果表明:X水平斜撑能够提高装配式结构的空间协调作用,在水平力作用下能够满足框架结构的整体协同受力要求,并且有效地减小水平荷载作用下框架结构的侧向位移。由试验还得出:结构的水平剪力主要由剪力墙承担,装配式楼板的后浇面层在设防烈度8度以下的地区可以建议取消,试验验证了X水平支撑传递水平荷载的有效性。
In order to study how to improve the space effect of assembling monolithic composite floor and whether it can replace the cast-in-place surface layer of floor to reduce the quality of the structure, the quasi-dynamic test method is adopted to simulate the displacement of two-span and three- Two models of SJ1 and SJ2 with X-horizontal bracing assembly floor plate-SJ2 are compared with each other. The experimental results show that the X-level bracing can improve the space coordination of the fabricated structure, and can meet the requirements of the overall coordinated force of the frame structure under horizontal force, and effectively reduce the lateral displacement of the frame structure under the horizontal load. The test also shows that the horizontal shear force of the structure is mainly borne by the shear wall, and the post-poured surface layer of the assembled floor can be canceled in the area where the fortification intensity is below 8 degrees. The validity of the horizontal load of X-level support is verified .
