中文摘要：
完成了8个1/2比例的型钢混凝土（SRC）柱在低周反复荷载作用下的试验研究。对试件塑性铰区域的弯曲变形和剪切变形进行了量测,通过量测数据计算不同变形成分对SRC柱层间位移的贡献并分析了其随加载过程的变化规律。试验研究表明,SRC柱塑性铰区的弯曲变形是引起层间位移的主要变形分量,塑性铰区的剪切变形对层间位移的贡献相对较小。本文成果可为SRC结构基于性能的抗震设计提供参考。
英文摘要：
Eight half scaled core steel reinforced concrete（CSRC） columns were tested under cyclic loading.The flexural and shear deformation of SRC columns at plastic hinge were measured.Based on the test data and a simplified analysis of the global deformation,the percentage of each deformation component due to the plastic flexural deformation and shear deformation of plastic hinge and their characteristics were investigated.It is indicated that the story drift is mainly caused by the flexural deformation of plastic hinge.The contribution of the shear deformation of plastic hinge to the story drift is relatively small.This paper can be referenced for the performance-based seismic design and engineering practice of CSRC structures.
