北京市劲松小区框架轻扳试验楼,采用了装配整体式板柱框架节点。楼板为300号陶粒混凝土角点支承双向预应力密肋填芯板,柱子为有柱帽的300号普通混凝土空心柱,板角伸出钢筋相互搭接加焊,上下柱钢筋也相互焊接,板缝内上下配置钢筋,在板柱交接处及板缝内现浇350号普通混凝土整体连接。这种装配整体式板柱节点的设计计算资料和经验都比较缺乏,为了摸清其受力性能,尤其是楼板间相互作用的情况,我们
Jingsong District, Beijing, the framework of light pull test building, using the assembly of the overall plate frame node. The slab is a 300-ceramic concrete corner support bidirectional prestressed dense rib cored plate. The column is a normal concrete hollow column with column cap No. 300. The plate corners extend the steel bars to overlap and weld, and the upper and lower column steel bars are also welded to each other. Steel plates are arranged on the upper and lower sides of the plate joints, and the general concrete No. 350 is cast in place at the intersections of the plate columns and the plate joints. The design and calculation data and experience of assembling assembled monolithic column nodes are relatively lacking. In order to understand its performance, especially the interaction between floors, we
