【摘要】 利用有限元软件ANSYS建模,对圆钢管混凝土在循环荷载作用下全过程进行了非线性有限元计算,以模拟地震作用对圆钢管混凝土实际受力性能。试验表明:圆钢管混凝土充分利用了钢管与混凝土两种材料的力学优势,是一种优良的结构体系。更多还原

【Abstract】 Modeling using finite element software ANSYS,made nonlinear finite element calculation to the whole process of CFST under cycle load,so as to simulate actual bearing performance of earthquake to round CFST.Experiments show that: round CFST made full use of mechanical advantage of the steel tube and concrete two kinds of material,it was a good structure system.更多还原
