摘要
基于有限位移理论的虚功原理,通过理论分析和对典型结构的分析,得到了预应力砼杆件的临界荷载.讨论了预应力、截面配筋率和偏心距对杆件临界荷载的影响.
In this paper,based on the principle of virtual work of finite displacement theory,the critical loads of members with prestress are developed by the analysis of several typical structures.These results make clear the influence of prestress on the critical loads.Meanwhile,a method of dealing with prestress is given,with its application to the stability analysis of structural engineering.
