The double reduced beam section (DRBS) connection is a newly developed steel moment connection. In this paper, the chaotic particle swarm optimization technique was utilized to optimize this connection for the best seismic performance. The resulting optimum DRBS connection shapes showed up to 39% better energy dissipation and up to respectively 50% and 55% lower rupture index (RI) and equivalent plastic strain (PEEQ) at the beam-column interface, compared to the conventional RBS connection. Also, the optimum design parameters determined in this paper led to up to a 28% increase in the objective function (energy dissipation) and up to respectively 36% and 38% decreases in the RI and PEEQ with respect to the original DRBS connection, indicating noticeable seismic performance enhancements. The results indicated that changing the size of the beam and column sections does not lead to any significant change in the optimal shape of the beam flange cut or the seismic performance of the connection.
