摘要
应用混凝土线性徐变理论的龄期调整弹性模量法,探讨了钢筋混凝土压杆徐变稳定性分析的静力法和有限元法.通过虚功方程导出了这种压杆徐变稳定性分析的单元刚度方程,并利用所研制的相应程序作了算例考核.
Applying the age - adjusted effective modulus method, this paper discusses the static method and finite element method for analysing the creep stability of reinforced concrete coulmns. By using of virtual work equations, formulas of finite element method are derived. At the end, an example is analysed with two methods respectively, which shows that the result of finite element method convergences very quickly and has a good accordance with that of static method.
