摘要
本文利用极限理论推导了单向压弯时方钢管混凝土构件截面强度的N M相关关系 ,进而提出了单向及双向压弯时截面强度的简化计算公式。并将数值分析结果及试验值与公式值进行了比较 ,证明了简化计算公式的适用性。
In this paper, N M correlation for strength of concrete filled rectangular steel tubular coulmns under eccentric compression is deduced with critical theory and the simplified calculation formulae for eccentric compression are put forward. To verify their validity, numerical analysis results and test data are compared with the formulae.
