摘要：

In this paper seismic design optimization of steel moment frames is studied. In addition to element sections, the connection types (simple or rigid) are considered as design variables. Element stresses and story drifts are limited according to the AISC-LRFD design criteria. The heights of the bottom and top columns, heights of the two intersecting beams and the flange widths of beams and columns are compared at each joint in order to control the constructional requirements. Compactness and slenderness for sections and column to beam plastic moment capacity ratio for joints are checked according to seismic provisions of AISC. Optimum results of three examples are obtained utilizing the enhanced colliding bodies optimization and particle swarm optimization and the performance of these algorithms for the present optimization problem are compared.
