为了研究钢骨混凝土异形柱的受力性能和影响因素,在试验研究的基础上编制了非线性分析程序。对非线性分析得到的承载力与试验进行比较可知,二者误差较小。分析了加载角、偏心距、含钢率、混凝土强度等级以及肢长厚比对构件承载力的影响。结果表明:含钢率的变化对构件的极限承载力影响明显,且极限承载力随着截面含钢率的增大而增大。最后对十字形实腹式钢骨混凝土异形柱实用设计方法进行了探讨。 In order to study the mechanical properties and influence factors of SRC special-shaped columns, a nonlinear analysis program was developed based on the experimental study. The comparison between the bearing capacity obtained by nonlinear analysis and the experiment shows that the error between the two is small. The influence of loading angle, eccentricity, steel content, concrete strength grade and limb-thickness ratio on the bearing capacity of the members was analyzed. The results show that the change of steel content has obvious influence on the ultimate bearing capacity of the component, and the ultimate bearing capacity increases with the increase of the steel content in the section. Finally, the practical design method of cruciform concrete-filled steel reinforced concrete special-shaped column was discussed.
