Research on static axial compression of rectangular steel tube concrete

针对矩形钢管混凝土轴压短柱其钢管对核心混凝土的约束作用对轴压构件的承载力影响的问题,通过理论计算与试验数据分析对比,提出了用一个一次二项式来拟合相关系数与截面形状系数的关系及用截面形状系数来修正圆钢管混凝土轴压短柱承载力公式在实际应用中的可行性。

According to the bearing capacity influence problem of the confinement effect of static axial compression of rectangular steel tube concrete steel tube to the core concrete to axial compression member, through theoretical calculation and test data analysis and comparison, proposed using a binomial to fit the relationship of correlation coefficient and cross section shape coefficient Ф and the feasibility of using cross section shape coefficient Ф to correct the bearing capacity formula of static axial compression of circular steel tube concrete in practical application.
