摘要: 为降低由于填充墙而出现的刚度增大效应,提升无浆填充墙框架整体耗能能力,设计了一种无砂浆填充墙框架结构,进行了无浆填充墙框架、有浆填充墙框架与相应 RC 纯框架结构的拟静力试验,比较了不同填充墙结构形式下的骨架与滞回曲线、刚度、强度退化曲线及耗能能力. 研究结果显示:无浆填充墙框架结构在弹性阶段耗能良好,附加给框架结构的刚度很小;在强度退化方面,无浆填充墙框架结构较有浆填充墙框架结构好;无浆填充墙框架结构具有良好的抗震性能.

Abstract: In order to reduce the effect of stiffness increase due to the infilled wall and improve the overall energyconsumption capacity of the frame without mortar infilled wall, a frame structure without mortar infilled wall was designed,the quasi-static test of the frame without mortar infilled wall, the frame with mortar infilled wall and the corresponding RCpure frame structure were carried out, and the skeleton and hysteretic curve, stiffness, strength degradation curve andenergy consumption capacity under different types of infilled wall structure were compared. The research results show thatthe frame structure without mortar infilled wall has good energy consumption in the elastic stage, and the stiffness added tothe frame structure is very small. In terms of strength degradation, the frame structure without mortar filled wall is betterthan that of the frame structure with mortar filled wall. The frame structure without mortar filled wall has good seismicperformance.

Keywords:pure frame; frame without mortar infilled wall; frame with mortar infilled wall; quasi-static test; rigidity;energy consumption capacity
