摘　　要：为研究清水混凝土外墙挂板与主体结构连接节点在水平荷载(风荷载、地震荷载)作用下的受力性能、变形能力和破坏损伤模式,对2组节点试件进行平面内及平面外抗侧试验,分别测定清水混凝土外墙挂板连接节点平面内、平面外的受力性能与变形能力。试验结果表明:节点试件变形能力可达到1/42位移角,加载过程中连接角钢均未屈服,可满足大震下外挂墙板连接节点的受力与变形要求。试验结论为推广应用此种挂板连接节点提供了一定的参考依据。To study the mechanical performance, deformation capacity and damage mode of the connection joints between prefabricated fair-faced concrete external wall hanging panel and main structure under horizontal load(wind load and earthquake load), the in-plane and out-plane earthquake resistance tests are carried out on two groups of joint specimens, and the in-plane and out-plane mechanical performance and deformation capacity of the joints are measured respectively. The test results show that, the deformation capacity of the joint specimens can reach 1/42 displacement angle, and the connecting angle steel does not yield during the loading process, which can meet the requirements of stress and deformation of the external wall panel connection joints under strong earthquake. The test conclusion provides a certain reference for the popularization and application of this type of hanging panel connection joints.
