Abstract

This paper studies the elastic seismic responses of a long span gable trussed structure and discusses two methods for estimating the static seismic loads. First, a set of seventy two trussed structures are designed using the four fundamental geometric parameters; span, height of the substructure, ratio of span to depth and ratio of rise to half-span. Then, for all of the structures, the eigen-value and earthquake response analyses are carried out. Based on the results, two methods of estimating the static seismic loads are proposed depending on the magnitude of equivalent modal weight. Finally, accuracy of the static forces is examined by comparing the estimated values with those obtained using direct dynamic analysis.
