带肋薄壁方钢管再生块体混合柱力学性能研究

摘要

Based on the circumstance with the same steel consumption, the paper undertakes the axial test on the ribbed thin-walled square steel pipe and the regeneration block mixed column of the enlarged section thin-walled steel pipe, and indicates the ultimate axial pressure bearing ca- pacity of the ribbed trials and the enlarged section one are improved greatly by the comparison and analysis,%在用钢量相同的情况下，进行了带肋薄壁方钢管和加大截面薄壁方钢管再生块体混合柱的轴压试验，通过对比分析，带肋试件和加大截面试件的极限轴压承载力均有很大的提高。
