摘　　要：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 commonly used as the primary component in light wood structures to resist the lateral loads. The stiffness of the beam connected with slabs for load transmission has a direct impact on the lateral resistance and failure mode of wood frame shear walls. Furthermore,the effect is greater when hold-downs are not fixed at the ends of the walls and openings. The wood frame shear wall was loaded by a new load transmission beam which was located in the lateral side of the slab. Through lateral loading test studies on 12 wood frame shear walls with different details,performances of the single piece wood structure shear walls without vertical loads were studied,including failure mode,load-displacement curve,elastic lateral stiffness,shear strength and ultimate displacement. Test results of wood frame shear walls with different details were compared and analyzed. It is concluded that wall column spacing has great impact on the mechanical properties of the wall while nail spacing has little impact.
