摘　　要：为了研究填充剪力墙梁柱式木框架混合结构抗侧力性能,制作了两种梁柱框架节点,采用单调和往复加载的试验方法,对内填钢板螺栓连接和植筋连接梁柱式木框架节点的受力性能进行试验研究.采用SAP2000软件建立填充剪力墙梁柱式木框架混合结构的有限元分析模型,分析了混合结构的抗侧力工作机理和性能.研究结果表明:内填钢板销式连接框架节点初始阶段刚度近似为零;植筋连接框架节点具有较高初始刚度和承载力;木框架侧移变形能力是剪力墙的2～3倍,填充剪力墙梁柱式木框架混合体系的抗侧力承载力不能充分利用木框架的抗侧力承载力,出现明显的框架抗侧力滞后现象;混合体系抗侧力性能更加接近于剪力墙,可以按剪力墙的要求分析;混合结构抗侧力承载力为组成框架和剪力墙承载力之和,可以采用本文提出的理论分析模型计算.The performance of slotted-in steel plates dowelled and glued-in bar post-to-beam connections were tested with monotonic and reversed cyclic loading protocols. The performance of different types of filled-in shear wall hybrid post-and-beam frame constructions was studied using a finite element model that was developed with SAP2000. Results indicate that the initial stiffness of slotted-in steel plates dowelled post-to-beam connections approximately equals to zero and glued-in bar post-to-beam connections have relative high initial stiffness and resistance capacities. The racking displacement capacity of post-and-beam frame is 2 ~ 3 times than that of shear wall, the lateral load resistance capacity of post-and-beam frame cannot be fully employed in hybrid constructions. The hybrid constructions behave more similar to shear walls. Based on the analysis of the tests, mathematical models verified by experimental tests for the hybrid constructions were developed and proposed.
