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,研究木框架剪力墙的抗侧力性能是研究轻型木结构抗侧力性能的关键。木框架剪力墙抗侧力性能试验研究时,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。本文采用荷载铰接传递梁、连续刚性荷载传递梁以及一种新型、位于顶梁板侧边的荷载传递梁对三片不同类型的足尺木框架剪力墙进行了单向、反复加载试验研究,其中一片为无洞口剪力墙、一片开门洞剪力墙、一片开窗洞剪力墙,重点研究其破坏形态、抗剪强度、极限位移、弹性抗侧刚度,并对三种荷载传递梁木框架剪力墙抗侧力试验结果进行了分析。Wood frame shear walls are commonly used as the primary component of the lateral load resisting system. The research on the performance of the walls under lateral load is a key point in light wood structures. The stiffness of load spreader has a direct impact on the failure mode and lateral resistance of wood frame shear walls in shear wall tests. Furthermore, it is more affected when hold-downs are not fixed at the ends of the walls and openings. A new load spreader setup is designed and used to conduct the test research under monotonic and cyclic protocol. The test specimens are three full size wood frames shear walls; one is a standard wall, one with door opening and the other one with a window opening. The failure mode, shear strength, ultimate displacement and lateral displacement stiffness are studied. The test results of wood fram shear walls with three different types of load spreader are analysed.
