预制混凝土剪力墙结构振动台试验研究
Study on shaking table test of precast concrete shear wall structure
摘要
Abstract
In order to investigate seismic properties of precast concrete shear wall (PCSW) structure , two 1/4 scale shaking table tests were designed and conducted ,which were a PCSW structure and a cast‐in‐situ concrete shear wall structure (CCSW) .Firstly ,the new horizontal connection of precast shear wall was proposed and introduced detailedly .Then ,the dynamic properties and structural re‐sponses of the two structures were compared using shaking table test .The experimental results indi‐cate that the new horizontal connection of precast shear wall is useful and effectively ,which can meet the connection requirement under rare earthquake .During the earthquakes ,the PCSW structure and the CCSW structure have similar failure process and failure shapes .With the increase of peak ground accelerations ,damage is accumulated in the two strucutures ,and the frequencies of the PCSW struc‐ture and the CCSW structure decline ,damping ratios of the tw o structures increase;the top storey ab‐solute accelerations ,shear‐weight ratios ,inter‐storey drifts increase nonlinearly .The PCSW structure and the CCSW structure have similar absolute acceleration distribution ,inter‐storey drift distribution , shear force distribution ,and shear‐weight ratio distribution .关键词
