Abstract

In recent papers, the authors have presented Generalized Beam Theory (GBT) formulations specifically designed for performing efficient (i) linear analyses of steel-concrete composite bridges [1] and (ii) elastoplastic collapse analyses of thin-walled steel members [2, 3]. This paper presents an extension of these previous formulations that includes non-linear reinforced concrete material behaviour, aiming at analysing, accurately and efficiently, steel-concrete composite beams. In particular, steel beam and rebar plastification is implemented, together with concrete cracking/crushing and shearlag effects. Several illustrative examples are presented and discussed. For validation and comparison purposes, results obtained with shell/solid finite element models are provided.
