✦ Synopsis

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.

## Abstract The analysis is aimed at determination of displacements in elastic‐perfectly plastic frames, in the case of monotonically increasing loads. Spread of partial plasticity from hinges and change of geometry on the conditions of equilibrium are not included. Extremum energy principles and l
