RESUMO

A composite joint is a joint between a composite beam and a steel or composite column in which reinforced concrete slab is take into account. The moment-rotation relationship of composite joints depends on a significant number of parameters besides the type and configuration of the steel connection, as for example: the amount of steel reinforcement of the slab and the degree of interaction between the slab and the steel beam section. Based on the Eurocode 3 method for bare steel connection (Components Method), some methods have been developed for prediction the moment capacities of composite connections. I this work, an adaptation of one of these methods has been developed in which steel sections and connections details common in Brazil are considered. A short experimental program was planed in order to understand the composite behaviour of extended end-plate composite beam-column connection. The test specimens were configured as cruciform type and cantilever type. Finally, a Finite Element model was built in Ansys software. The numerical modeling was found to have good approach with experimental results. Some analyses are done involving experimental, numerical and analytical results.
