摘　　要：在实验基础上,比较了矩形钢管混凝土轴心受压和偏心受压构件应用方钢管混凝土构件在GJB(2000)中轴压和压弯构件承载力的计算公式的差异;提出了在方钢管混凝土轴压承载力计算公式基础上的修正公式,即将原公式中的约束效应系数考虑截面长宽比的影响后乘以折减系数0 9.修正公式可供矩形钢管混凝土轴心受压柱参考.Comparisons are made between experimental bearing capacities of concrete-filled-rectangular steel tube columns under axial and eccentric compression and the theoretical results calculated with formulas in code GJB(2000) for concrete-filled-foursquare steel tube columns under corresponding loading conditions. Modified formulas, based on formulas for concrete-filled-foursquare steel tube columns, are presented by timing the original coefficient with 0.9. The modified formulas provide reference for calculation of bearing capacities of concrete-filled-rectangular steel tube column under axial compression..
