钢管高性能混凝土核心柱正截面承载力叠加计算方法

Method of superposition calculation on bearing capacity of normal section of high performance concrete-filled steel tubular core column

对钢管高性能混凝土核心柱的概念及其合理性进行了分析,对钢管高性能混凝土核心柱力学性能及主要影响因素进行了探讨,借鉴塑性理论下限定理提出其正截面承载力的叠加计算公式,并进行了案例计算。

The concept and reasonability of high performance concrete-filled steel tubular core column are analyzed herein,and then the mechanical behavior of the column and the factors of main impacts on it are discussed as well,furthermore,a formula of superposition calculation on the bearing capacity of its normal section is put forward along with the calculation made on an actual case in accordance with the lower bound theorem of the plastic theory.
