摘要
在14根方钢管混凝土构件试验的基础上,分析了初应力系数、荷载偏心率、混凝土强度、试件长细比等因素对承载力的影响,给出了钢管初应力对方钢管混凝土压弯构件承载力的影响系数,采用ANSYS有限元分析程序进行了非线性全过程分析.
Based on 14 specimen tests of concrete filled square steel tubes（CFST）, the effects of the initial stress coefficient, load eccentricity ratio, strength of concrete, ratio of slenderness of test specimens, etc. on bearing capacity are analyzed, and the effect coefficient of the CFST is also given. The nonlinear full range analysis is performed by the FEA software of ANSYS.
