Abstract
Abstract
Nowadays, due to savings requirements, the heights of floor systems in multi-story buildings are reduced. To ensure passage of installation within a floor depth, a solution considering web openings is usually adopted in steel-concrete composite structures. Owing to the presence of web openings, the structural performance of a bearing member is affected not only in the final stage but also during the construction. Hence, the main purpose of this research is to evaluate the impact of web openings on the lateral-torsional buckling resistance of the steel part of composite girder in the erection stage. Comparison of lateral-torsional resistance of the steel girders with web openings derived by the analytical approach with results obtained by numerical model is presented and discussed.
