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 most important Japanese side beam column structure of the anti-side members, the anti-side force depends on the performance of the panel nail connection. According to the Japanese-style shear wall structure, shear-wall cladding nail-nailed specimens were made. Monotonic and reciprocating loading tests were carried out respectively. The failure modes, load-displacement curves and bearing capacity of the nailed joints were analyzed and the correlation curves were fitted and analyzed. The research shows that the loading method has a significant effect on the test results of nail connection; the connection of nail lamination plywood and radiata pine / poplar composite plywood is good, and the two are similar in bearing capacity.
