高轴压比高强混凝土框架柱抗震性能尺度效应分析
Scale Effect Analysis of Seismic Behavior of High Strength Concrete Frame Columns with High Axial Compression Ratio
摘要
Abstract
According to the test results of the seismic behavior of high strength concrete frame columns with high axial compression ratio,the influence of section size on the bearing capacity,hysteretic curve,skeleton curve and ductility of frame columns has been analyzed,and the changing rules of the longitudinal reinforcement,stirrup and concrete have been discussed.The study shows:the larger the size of column section,the worse the bearing capacity and ductility are;the hysteretic curve of large scale high-strength concrete frame column shows obvious pinching effect,and the skeleton curve of large size high-strength concrete frame column is steeper;with the increase of axial compression ratio and concrete strength,the maximum tensile strain of longitudinal reinforcement decreases,and the tensile strain and compressive strain of concrete increase rapidly;single leg brace hoop and common stirrup have the same effect;the section size is larger,the greater the stirrup strain.关键词
