Earthquake-resistant design of structures using probabilistic analysis and performance-based design criteria is an emerging field of structural engine-ering. These new analysis and design methodologies are aimed at improving the existing practice and design codes for better prediction of the structural performance. In this paper, a robust and efficient methodology is presented for performing reliability-based structural optimum design of steel frames under seismic loading. The optimization part is realised with evolution stra-tegies, while the reliability analysis is carried out with the Monte Carlo simu-lation method incorporating the latin hypercube sampling technique for the reduction of the sample size. The probability of failure of the frame struc-tures, in terms of interstorey drift limits, is determined via the multi-modal response spectrum analysis.
