摘要: 為降低由于填充墻而出現(xiàn)的剛度增大效應(yīng),提升無漿填充墻框架整體耗能能力,設(shè)計了一種無砂漿填充墻框架結(jié)構(gòu),進行了無漿填充墻框架、有漿填充墻框架與相應(yīng) RC 純框架結(jié)構(gòu)的擬靜力試驗,比較了不同填充墻結(jié)構(gòu)形式下的骨架與滯回曲線、剛度、強度退化曲線及耗能能力. 研究結(jié)果顯示:無漿填充墻框架結(jié)構(gòu)在彈性階段耗能良好,附加給框架結(jié)構(gòu)的剛度很小;在強度退化方面,無漿填充墻框架結(jié)構(gòu)較有漿填充墻框架結(jié)構(gòu)好;無漿填充墻框架結(jié)構(gòu)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
