In the paper the mathematical model of the optimization problem of limit and shakedown analysis for composite plane frames, containing elastic-plastic and brittle elements under low-cyclic loading, is proposed. It is assumed that the load varies randomly within the specified domain, and limited plastic redistribution of forces in such structures occurs. An example of the shakedown analyses of the composite frame is given.

W pracy przedstawiono model matematyczny optymalizacji nośności granicznej i przystosowania płaskich ram zespolonych stalowo-betonowych, zawierających sprężysto-plastyczne i kruche elementy. Przyjęto, że obciążenie zmienia się w dowolny sposób w określonym obszarze. W takich konstrukcjach po obciążeniu niskocyklowym występuje ograniczone plastyczne wyrównanie sił wewnętrznych. Podano przykład analizy przystosowania ramy zespolonej.
