［摘要］为研究高强箍筋约束足尺混凝土柱的抗震性能，进行了4个试件的低周反复荷载试验，测得了荷载位移滞回曲线，研究了各试件的破坏模式、滞回性能、骨架曲线、延性性能及耗能能力。试验结果表明：高强钢筋用作箍筋时，足尺混凝土柱具有良好的延性和大的塑性变形能力，耗能能力强，抗震性能优越。［关键词］抗震性能; 足尺; 混凝土柱; 高强箍筋中图分类号：TU375.3 文献标识码：A 文章编号：1002-848X(2015)20-0057-06
Experimental study of seismic performance of full-scale concrete columns with high-strength stirrupShao Yunda1,2, Li Zhenbao1, Xie Yongping1(1 Key Laboratory of Urban Security and Disaster Engineering of Ministry of Education, Beijing University of Technology, Beijing 100124, China; 2 The Open University of China, Beijing 100039, China)Abstract: In order to study the seismic performance of full-scale concrete columns with high strength stirrup, low cyclic loading tests of 4 specimens were completed and load displacement hysteretic curve was measured. The failure mode, hysteretic behavior, skeleton curve, ductility and energy dissipation capacity were analyzed. The test results show that when high strength steel bar is used as stirrup, the full-scale concrete column has good ductility and large plastic deformation capacity, strong energy consumption and dissipation capacity with excellent seismic performance.Keywords: seismic performance; full-scale; concrete column; high-strength stirrup
