钢管混凝土构件截面刚度的规程对比分析

The comparison among codes about the section rigidity of concrete-filled steel tube members

以圆钢管混凝土、方钢管混凝土为研究对象,对国内外常用规范关于轴压刚度和抗弯刚度进行详细的比较分析,结果表明,我国常用规范关于轴压刚度相差很小,但抗弯刚度差别明显,而日本常用规范较我国规范显著偏小,在结构设计与分析时应合理比较,确保结构更安全。

The analysis about the axial compressive rigidity and the bending rigidity of concrete-filled steel tube members with circular section and square section,was conducted from common codes at home and abroad.The results showed,axial compressive rigidity from codes at home was nearly equal,but bending rigidity was uncertain,while that from Japan code were small obviously,meaning that some rational comparison should be conducted for selecting rational codes to make sure projects safe during designing.
