摘要
从钢管混凝土柱的工作机理出发,研究CSFT中钢材和混凝土的本构关系。分别采用Von Mises和Drucker-Prager屈服准则分析钢材和核心混凝土的强度及屈服问题,并由此推导出钢管混凝土柱的轴压承载力计算公式。
Based on the principle of the concrete filled steel tube, study is carried on the constitutive relation of concrete and steel in CSFT. The axial compression bearing capacity of CFST is obtained by analyzing the strength and yieled problem with Von Mises and Drucker-Prager criterion.
