木框架剪力墙是轻型木结构抵抗侧向荷载的重要构件,与顶梁板相连的荷载传递梁刚度对木框架剪力墙的抗侧力性能以及破坏模式有直接影响,当木框架剪力墙墙端以及墙中洞口边未采用墙端锚栓时,这种影响更甚。采用一种新型的、位于顶梁板侧边的荷载传递梁对木框架剪力墙进行加载,通过对12片不同构造木框架剪力墙的侧向加载试验,研究了木结构单片剪力墙在无竖向荷载作用下的破坏模式、荷载-位移曲线、弹性抗侧刚度、抗剪强度、极限位移等性能。并对不同构造下木框架剪力墙试验结果进行对比分析,认为墙骨柱间距的改变对墙体受力性能有较大影响,而钉间距的改变对墙体受力性能影响不大。
Wood frame shear wall is an important component of light wood structure to resist lateral load. The stiffness of load transfer beam connected with the roof beam has a direct impact on the lateral resistance performance and failure mode of the wood frame shear wall. When the wood frame shear force This effect is even worse when wall anchors are not used on the wall ends and in the wall openings. A new type of load transfer beam located on the side of the roof beam was used to load the wooden frame shear wall. Through the lateral loading test of 12 shear walls with different construction wooden frames, Failure mode, load - displacement curve, elastic lateral rigidity, shear strength and limit displacement of the wall without vertical load. The comparison of the test results of the wooden frame shear walls with different structures shows that the change of the spacing between the wall and the column greatly affects the mechanical performance of the wall, while the change of the nail spacing has little effect on the mechanical performance of the wall.
