Abstract

A unified equations system for analysis of elastic- plastic frame structures under given external loads, thermal effects, supports displacements and known plastic strains is obtained by using a concept of distorsion. Distorsion, concentrated at the main (bounding) nodes of finite equilibrium elements enables the uniformly load p applied at the element to be changed by nodal forces. Relations between unified matrix equations system and extremum energy principles are shown.
