Abstract The objective of this paper is to perform reliability analysis of space frames under seismic loading. In order to produce the dynamic loads a number of random accelerograms is produced from the elastic design response spectrum of the region. Structural reliability analysis is performed using the Monte Carlo Simulation (MCS) method. The results obtained for a realistic structural problem indicate the applicability of the proposed procedure.
