为研究加气混凝土墙板和墙板钩头螺栓节点在风荷载作用下的工作性能,对8块加气混凝土板材进行节点的平面外拉拔试验,分析加气混凝土板材的配筋和垫片半径对传统的钩头螺栓节点面外承载能力的影响。研究表明:钩头螺栓节点随着垫片半径的增加极限承载能力增加,同时板材配筋面积的增加也直接影响到承载能力。钩头螺栓节点基本能满足北京地区90 m高层建筑围护体系在正常使用极限状态下对风荷载的要求。
In order to study the working performance of the joints of aerated concrete wallboards and the hook bolts of wallboards under the action of wind load, the out-plane pull-out test of eight aerated concrete panels was carried out to analyze the reinforcement and gaskets of aerated concrete panels The Influence of Radius on the Out-of-plane Load Capacity of Conventional Hook-and-Bolt Nodes. The results show that the ultimate load-carrying capacity of hook-and-bolt joints increases with the increase of shim radius, and the increase of plate reinforcement area also directly affects the bearing capacity. Hook bolt node can basically meet the Beijing 90 m high-rise building envelope system in the normal use of the limit state of the wind load requirements.
