［摘要］為研究高強箍筋約束足尺混凝土柱的抗震性能，進(jìn)行了4個試件的低周反復(fù)荷載試驗，測得了荷載位移滯回曲線，研究了各試件的破壞模式、滯回性能、骨架曲線、延性性能及耗能能力。試驗結(jié)果表明：高強鋼筋用作箍筋時，足尺混凝土柱具有良好的延性和大的塑性變形能力，耗能能力強，抗震性能優(yōu)越。［關(guān)鍵詞］抗震性能; 足尺; 混凝土柱; 高強箍筋中圖分類號：TU375.3 文獻(xiàn)標(biāo)識碼：A 文章編號：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
