摘要
A unified equations system for analysis of elastic-plastic frame structures under given thermal effects supports displacements and known plastic strains is obtained by using a concept of distortion. Distortion, concentrated at the main (bounding) nodes of finite equilibrium elements, enable the uniformly load p applied at the element to be changed by constant loads. Relations between unified matrix equations system and extremum energy principles are shown. Copyright (C) 1996 Elsevier Science Ltd.
