【摘要】 本文以有限元法为基础(1),利用电子计算机进行复杂刚架的塑性分析(3)。从中能清楚地了解到在加载过程中塑性铰出现的位置及次序,直到刚架形成机构的全部过程。在计算过程中,确定荷载的增量以后,可求得荷载和位移关系。从而找出极限荷载和极限位移,这就为解决复杂刚架的极限设计提供了现代手段。更多还原

【Abstract】 On the basis of finite element method, The plastic analyses of complex frames are carried out by electric computer program in this paper. In the loading process the seat and order of plastic hinge of frame can be clearly found out until the mechanism of frame in the total loading process has been formed After the load increments has been obtained, the ultimate load and linit displacement can be determined. So modern method of solving limit design of complex frames has been provided in this paper.更多还原
