Simplified approach for the long-term behaviour of timber-concrete composite beams according to the Eurocode 5 provisions
The aim of this paper is to propose a simplified yet accurate solution for the long-term behaviour of TCC’s. The approach will allow the designer to account for the whole loading history of the structure including concrete shrinkage, effect of props during construction, and inelastic strains due to environmental variations. The accuracy will be assessed by comparison with numerical solutions on a number of TCC’s of technical interest. Finally the influence of different environmental conditions such as outdoor and heated indoor conditions on the long-term performance will be discussed.
