Due to architectural advantages and, more recently demonstrated, to the applicability to seismic design, the slim-floor moment-resisting beam-to-column joints could be an efficient solution to mid- and high-rise structures. The integration of the slim-floor beam into relatively tall steel and composite structures designed to withstand inertial forces caused by seismic action was achieved on a two-dimensional Dual-Concentrically Braced Frame system. The central focus of the study is the seismic performance evaluation of this frame with nonlinear static and dynamic analyses. The analyses’ results evidenced an adequate seismic performance, proof of which were the following: damage sustained at each Limit State, progressive development of plastic mechanisms, limited inter-storey drifts and maximum joint rotation demand lower than experimentally proven. These results demonstrate the possibility of using slim-floor beam-to-column joints in seismic-resistant structures.
