斜向水平反复荷载作用下L形截面柱抗震性能试验及损伤分析
SEISMIC BEHAVIOR EXPERIMENT AND DAMAGE ANALYSIS ON RC L-SHAPED COLUMNS SUBJECTED TO CYCLICAL LOADING
【摘要】 试验设计了三组6个钢筋混凝土L形截面柱试件,施加斜向水平低周反复荷载。观测了破环过程,量测了关键阶段的裂缝宽度,采集了力-位移滞回曲线等相关数据。应用建议的损伤评价模型对其进行损伤量化分析。研究结果表明:加载角对L形截面柱的损伤影响较为显著,设计应沿工程轴方向和斜向45°进行抗震验算。
【Abstract】 Anti-seismic behavior and damage analysis of L-shaped section cross column are investigated based on 3 groups of 6 specimens subjected to cyclic loading.The include mechanical performances such as bearing capacity, failure pattern,hysteretic property,declining stiffness etc,are analyzed by the experiments.Research results indicate anti-seismic calculations of the columns should be according to direction of engineering axial and degree 45.
