摘　　要：为了进一步研究方钢管-钢骨高强混凝土压弯构件的力学性能,作者运用合成法和有限条带法相关知识,编制了方钢管-钢骨高强混凝土压弯构件分析程序。程序计算结果与试验结果吻合较好;在此基础上,进一步分析了长细比、配骨率、套箍率变化对压弯构件承载力的影响规律;最后通过对大量数值计算结果的回归分析,得出了实用的压弯承载力计算公式。对典型试件的计算结果表明:该计算方法简单有效,且具有较好的精度。To study in detail the property on compression-bending of square steel tube filled with steel-reinforced high-strength concrete, the authors have developed a nonlinear analysis of computer program based on theory of the eomposting method and limited strip unit method. The calculated results of the program agreed well with experimental results. In addition, the influences of slenderness ratio, stirrup ratio and steel-reinforced ratio are also analyzed. Through analyzing the calculated results, a readily formula is obtained. Numerical results for typical members show that the method is simple, efficient and accurate.
