摘要
为了探究方钢管约束再生塑料混凝土中长柱的轴压力学性能,设计再生塑料取代率和试件长细比为变化参数,完成了7个试件的轴压性能试验,分析了试件的受力全过程和试件的荷载-位移曲线,研究了再生塑料取代率、试件长细比对方钢管约束再生塑料混凝土中长柱的荷载-位移曲线、极限荷载、延性以及强度系数的影响。
In order to study mechanical properties of recycled plastic quare tube confined concrete middle long columns under axial compression, 7 specimens are designed for axial compression test with slenderness ratio of specimen and recycled plastic replacement ratio as the main parameters, to combin the loading process of specimens and force-displacement curve.Analyze slenderness ratio and recycled plastic replacement ratio to the effect on force-displacement curve,peak load,ductility and strength coefficient of recycled plastic quare tube confined concrete middle long columns.
