彩图制作了5组10片木框架剪力墙分别进行单向和反复荷载试验,研究了剪刀撑及不同覆面板对剪力墙的抗剪强度、弹性抗侧刚度、极限位移、耗能的影响。试验数据说明:增加剪刀撑的墙体最大墙骨柱上拔量仅为未加剪刀撑的对照墙体墙的22.7%,剪刀撑对于抑制墙骨柱上拔的现象有显著作用,能控制墙体面板钉连接破坏先于墙骨柱连接破坏;而且剪刀撑还能增大墙体刚度,约束墙体位移。此外,试验各项参数表明:采用国产胶合板作为覆面板的墙体的抗剪性能良好,说明国产胶合板可以替代OSB板应用于剪力墙制作;而采用国产花旗龙板作为面板的墙体抗剪强度远远低于GB50005-2003《木结构设计规范》中采用木基结构板材的剪力墙抗剪强度设计值(fvd为4.7kN/m)的指标要求,建议在实践中仅作为强度储备。
Five sets of 10 pieces of wood frame shear wall were made for unidirectional and repeated load tests respectively. The shear strength, elastic lateral stiffness, ultimate displacement and energy dissipation of shear walls were studied. influences. Test data shows that the increase of the scaffolding wall of the maximum wall column pull the amount of only no scaffolding control wall wall 22.7%, scissor strut for inhibiting the phenomenon of wall studs pull significant effect can control the wall Decrease in the connection of the panel nail before the connection of the wall and the column, and the scissor support can increase the rigidity of the wall and restrain the displacement of the wall. In addition, the test parameters show that: the use of domestic plywood as the cladding of the wall shear performance is good, indicating that domestic plywood can be used instead of OSB shear wall production; the use of domestic Citi-board as a panel wall shear The strength is much lower than the index requirement of the shear strength of the shear wall using wood-based structural plates (fvd is 4.7kN / m) in GB50005-2003 Code for Design of Timber Structures. It is recommended that in practice, it should be used as the strength reserve only.
