Abstract: This paper develops a modified SRSS Method which allows a designer to select the reliability that he wishes to realize in each of the various elements of a given structure subjected to earthquake excitation. For 30 different artificial earthquakes, and three soil types; nine different, eight-story shear-type structures were designed, and their excursion ratios established using three different procedures: the SRSS Method, the Reliability Design Method; and a Modified SRSS Method. The Reliability Method was found to give the best results; the Modified SRSS Methods; next; and the SRSS Method, last. Soil type and Mass and Stiffness distributions were found to have little effect on the conclusions.
