| 摘 要： | 为了利用非线性推覆分析(Push-over)方法分析型钢偏心对型钢混凝土(SRC)柱承载力的影响,建立了SRC柱的Push-over分析模型,进行了偏心SRC柱的偏心受压试验和Push-over计算,验证了Push-over方法用于SRC柱分析的可靠性,并用Push-over方法分析了当SRC柱的长度和荷载作用位置等参数变化时,随着型钢偏心距的不同,SRC柱受力性能的变化情况,找出了型钢偏心对整柱承载力影响的变化规律.分析结果表明:当荷载和型钢同时偏心在截面形心轴的同一侧时,荷栽偏心距较小的SRC柱的承栽力随着型钢偏心位置的增大而减少,荷载偏心距较大的SRC柱的承栽力随着型钢偏心位置的增加而略有增加;当荷载和型钢偏心在截面形心轴的两侧时,无论荷载偏心距的大小,SRC柱的承载力随着型钢偏心位置的增加而增加,但其变化幅度不大.

| Abstract: | In order to analyze the influence of steel placement eccentricity on the bearing capacity of SRC columns using of nonlinear push-over analysis(Push-over) method,the Push-over model for SRC columns was established.In addition to the Push-over calculations,tests on the loading eccentricity of SRC columns were performed.The reliability of the Push-over method in analysis of SRC columns was validated.The present method was employed to study the properties of the SRC columns under loading with various column len... |
