Layered finite elements in the analysis of composite structures exposed to long-term effects

Anđelko Cumbo, Radomir Folić

Abstract

This paper presents the use of a numerical model based on layered finite elements in the analysis of stress and strain due to creep and shrinkage of concrete and relaxation of prestressing steel in statically indeterminate composite structures. The calculation algorithm allows significant changes in the structure through characteristic time intervals, in accordance with technological procedures used during realisation of works. The corresponding computer program adapted to daily practical engineering design is also developed.

Keywords
finite elements, composite structures, creep and shrinkage, relaxation, rheology
