摘要
通过对比试验 ,得出了自应力钢管轻骨料混凝土中核心混凝土的膨胀规律、自应力与含钢率的关系及自应力钢管轻骨料混凝土组合材料的优越性能 ,分析了轴心受压短柱的破坏过程。
Expansion rule of concrete core in self stress lightweight concrete filled steel tube,relationship between self stress and steel content ratio,and super performance of self stress lightweight concrete filled steel tube are gained through comparison test;damage process of short columns under axial load is analyzed.
