摘要
本文介绍了16根1/2比例的矩形钢管混凝土柱在常轴力和侧向低周反复荷载作用下的抗震性能试验研究,描述了构件的非线性发展过程及破坏形态,研究了不同试验参数(包括柱的轴压比、截面长宽比、含钢率、加载方向等)对矩形钢管混凝土柱抗震性能的影响。本文的工作可为矩形钢管混凝土结构的工程实践及相关标准的编制修订提供参考。
:An investigation of the seismic behavior of 16 concrete filled rectangular steel tubular (CFRT) column specimens subjected to reversed cyclic lateral loading combined with constant axial compression force is reported. The experimental process was recorded and the failure pattern of the specimens was also described herein. From the test results,the displacement ductility of tested specimens was presented. The effects of various parameters including axial compression ratio, steel ratio of the composite columns, depth-to-width ratio of section and loading direction on the seismic behavior of CFRT columns were studied as well.
