摘　　要：为了进一步研究胶合木框架-剪力墙的的抗侧力性能,本文针对胶合木框架、木剪力墙和胶合木框架-剪力墙三种结构开展了六项低周反复荷载试验研究,明确了破坏形态,分析了胶合木框架-剪力墙的受力机理,研究了不同结构形式的抗侧力性能以及墙体的连接、墙体开洞、跨高比等参数的影响。研究结果表明:胶合木框架-剪力墙的破坏模式以面板钉连接的破坏为主。胶合木框架与木剪力墙间的钉连接形式可靠,足以限制端部墙骨柱的上拔.胶合木框架-剪力墙的弹性抗侧刚度可视作胶合木框架以及木剪力墙的弹性抗侧刚度之和,但其极限承载力要大于胶合木框架与木剪力墙二者之和。Six reversed cyclic tests were conducted on three types of specimens for getting the lateral resistant per- formance of glulam frame-shear walls. Failure mode and load transferring mechanism were determined. The effect of different structural parametres were analysized, such as nail connections between glulam fame and wood shear wall, wall openning and aspect ratio. Results indicate that the prime failure mode of glulam frame-shear walls is the failure of sheathing nails. Nail connections linking glulam frame and wood shear wall can restrict the uplift of end studs reliably. Elastic lateral stiffness of glulam frame-shear wall is equal to the sum of glulam frame and wood shear wall, but peak load capacity of it is greater than the sum of the later two.
