摘要
为提高填充墙框架结构整体耗能能力,同时降低由填充墙引起的"刚度效应",提出了新型的无浆填充墙框架结构并进行了材性及拟静力试验。在材性试验中得到了无浆和有浆砌块抗压及通缝抗剪强度和钢筋混凝土的材料特性;在拟静力试验中将无浆及有浆填充墙框架与相应的钢筋混凝土纯框架对比得到了不同填充墙形式下框架结构的破坏过程及形态、结构滞回曲线,分析了新型无浆填充墙框架的受力机理。研结果究表明:无浆填充墙在框架弹性工作状态下耗能良好,并且对框架结构附加刚度很小,该结构形式抗震性能良好。
In order to improve the energy dissipation of the masonry in-filled frame structure, while decreasing the stiffening and strengthening effect of the infilling panels, a novel dry-stack masonry in-filled frame was proposed and a series of tests were performed. After evaluating the material parameters of both the masonry panel and frame experimentally, quasi static tests were carried on the dry stack masonry in-filled frame. By comparing the results with the bare frame and mortar in-filled frame, the damage development, failure modes, hysteretic behavior and the response mechanisms were studied. It is concluded that significant energy dissipation in the dry-stack in-filled frame can be obtained while keeping the frame under the elastic stage; the frame stiffening and strengthening effect of the dry-stack in-fill panel is not significant.
