摘要
剪力墙是日式梁柱式木结构最主要的抗侧力构件,其抗侧力取决于覆面板钉连接的性能。按照日式剪力墙构造制作剪力墙覆面板钉连接试件,分别进行单调和往复加载试验,分析钉连接的破坏模式、荷载-位移曲线及承载力,并对相关曲线进行拟合分析。研究表明,加载方式对钉连接测试结果有明显影响;落叶松胶合板和辐射松/杨木复合胶合板的覆面板钉连接性能均较好,二者承载力相近。
Shear wall is the main element to resist lateral force in Japanese-style post-and-beam structures,whose performance is affected by nail connections. Specimens of sheathing nail connections were manufactured based on Japanese-style shear wall and tested in monotonic and cyclic loading in groups.Load-displacement curves and bearing capacity were recorded during failure. The load-displacement curves and skeleton curves of the hysteresis curves were then fitted by an exponential function using the least square method. We found that performance of the nail connections with Larch plywood and Radiata pine/Poplar combination plywood all worked very well with similar bearing capacity,but was influenced by loading conditions.
