Vibration Behavior of Single Layer Latticed Cylindrical Roofs under Seismic Motion and the Static Load Modeling

Abstract

In this paper the earthquake response behavior of single layer latticed cylindrical shell roofs constituted with steel members has been numerically analyzed. The input waves are of the artificial earthquake waves having the various phase characteristics and target spectra. The relation between the strain energy and the various response quantities has been investigated in detail. An alternative seismic loading model for design has also been proposed and its applicability has been discussed.
