Results of push-out tests carried out on Hybrid Steel Trussed–Concrete Beams (HSTCBs) before and after the concretecasting are presented and interpreted. Firstly, in order to check the ability ofweldings before casting, tensiletests were performed on specimens reproducing different types of welded joints. Simplified design formulaewere used to predict their ultimate strength. Secondly, results obtained by push-out tests on specimen representativeof the beambefore and after the concrete casting are presented and discussed. Finally, simplified analyticalmodels proposed by the current European building codewere adapted to the specific typology to roughly predictthe ultimate strength obtained by push-out tests on specimens complete with concrete casting.
