Abstract

Timber-concrete composite girders are often used in the renovation of high-rise structures, and they can also be used in bridges. These systems are relatively complex to analyse as two materials presenting different stiffness and rheological properties participate in ensuring an appropriate bearing capacity. While the analysis of instantaneous deformations is clearly defined in Eurocode 5, the analysis of longterm deformations, which are often relevant, is not clearly defined. The objective of this paper is to present the analysis of a timber-concrete composite girder, taking into account instantaneous and long-term deformations in a relatively simple way, suitable for practical engineers.
