RESUMO

This work focused on the development of an efficient and economic composite building system. This was accomplished by the conception of two new composite major axis connection details for external and intermediate columns. The external column connection detail motivated the creation of a new connection element: the T-rib connector. The main purpose of this element is to transmit the reinforcement bars forces directly to the external columns in negative moment regions The present study also comprehended an nvestigation of two semi-rigid connections design models:the simplified analytical model of Kishi-Chen, [CHEN93], and the Eurocode 3 mechanical model,[EURO98], leading to further developments in both structural models. The first proposal extends the Kishi-Chen model, [CHEN93], for the external and intermediate columns connections investigated in this work. The second proposal incorporated the contributions of the T-rib connector, the web angles and the reinforcement bars on the EUROCODE3 model, since they were not originally taken into account. Both model were calibrated against the experimental results produced in the present investigation.An alternative solution for composite beams shear connectors was also developed. This solution consisted of an adaptation of the
