摘要
通过对7组14个木框架剪力墙试件进行单调和反复加载受剪性能试验研究,分析了不同墙骨连接方式、是否开设洞口及不同材料对木框架剪力墙的受剪承载力、弹性抗侧刚度、极限位移、耗能的影响。试验结果表明:墙骨柱采用榫接的连接方式,能有效避免在循环荷载作用下墙骨柱与底梁板钉接时的连接失效,保证墙体框架整体性;榫接连接对于提高墙体刚度、控制变形有显著作用;墙体开设洞口会显著降低墙体刚度,增大墙体的耗能能力。采用国产胶合板的墙体具有良好的受剪性能,可以作为进口OSB板的替代板应用于剪力墙建造。
Seven groups of shear walls with rabbet stud connection were tested under monotonic and cyclic loads respectively.The effects of different connection methods of studs,the opening and different materials on the strength,stiffness,ultimate displacement,stud lift and energy dissipation of the shear walls were studied.Experimental results show that joints with rabbet can avoid connection failure of nail connection under cyclic loads and ensure the integrity of the wall frame.The joints with rabbet can improve wall stiffness and limit the deformation of the wall.An opening in the wall can significantly reduce the stiffness and increase energy dissipation capacity of the wall.And plywood can be used to make shear wall in place of OSB because of the good shear performance in experiment.
