【摘要】 以长细比和偏心率为变化参数 ,共进行了十二个方中空夹层钢管混凝土偏心受压构件的试验研究。在确定组成方中空夹层钢管混凝土的钢材和核心混凝土应力 应变关系模型的基础上 ,利用数值解法对方中空夹层钢管混凝土压弯构件的荷载 变形全过程关系进行了分析 ,理论分析结果与试验结果吻合较好。最后 ,提出了方中空夹层钢管混凝土压弯构件承载能力实用验算方法更多还原

【Abstract】 The concrete?filled double skin steel tubular column with square section under eccentric loads is studied in the paper Twelve pieces of the column are tested in the lab of Fuzhou University Outside square tube is made of four welded plates;inside is a weldless steel tube The concrete is sandwiched in between the two tubes The main parameters varied in the study are the slenderness ratio and the eccentricity of load It is found that the computed load?displacement relations are in good agreement with that of the test one At last,a simplified formula for the bearing capacity of the column is proposed in the paper更多还原
