加气混凝土单元体外墙板抗震性能的试验研究
|
摘要
为研究加气摇摆减震节点连接下混凝土单元体外墙板的抗震性能,检验不同类型板缝嵌缝材料和外墙装饰面在地震作用下的变形状况,对一榀加气混凝土单元体内嵌外墙板进行拟静力试验。单元体板缝分别采用4种不同的嵌缝材料,饰面分别采用3种不同的施工工艺。试验结果表明:单元体外墙板可以提高围护结构的整体性,减小单个加气混凝土条板间的相对位移;摇摆减震节点能有效减小单元体外墙板在地震时的变形,降低围护结构受到的地震损伤;单元体外墙板和摇摆减震节点的结合,可以提高此类围护结构的抗震性能,保证墙体嵌缝材料和饰面在设防烈度地震作用下不裂。
To study the seismic behavior of autoclaved lightweight concrete( ALC) unit external wallboard with aerated swing damping joint and test the deformation of different types of caulking materials and exterior decorative surfaces under earthquake,a quasi-static test of aerated concrete unit embedded external wallboard was carried out.The seams of the unit plates were respectively made of four different caulking materials,and the decorative surfaces were constructed in three different construction processes. The test results showed that unit external wall board could enhance the integrity of the enclosure and reduce the relative displacement between individual aerated concrete slabs.Swing damping joint could effectively reduce the deformation of the unit external wallboard and the damage of the enclosure during the earthquakes. The combination of the unit external wallboard and the swing damping joint could improve the seismic behavior of the enclosure,so as to ensure that the wall caulking material and finishes do not crack under medium earthquake.
