Abstract
This study deals with a new application of shell structures called modular shell system in seismic areas. This structure consists of an assemblage of tubular and cupola units. These structures are built using reinforced concrete and have been proposed for reconstruction after the Bam earthquake. A complete three-dimensional modal spectral analysis, including both horizontal and vertical ground acceleration components, with all probable load cases, is carried out. The results show that this structural concept behaves well under seismic loading. Nevertheless, more attention should be given for opening frame regions. Due to the profound and efficient structural performance of shell concept, the shell system is suggested as a housing system for areas where the local site effect increases the high seismic risk.
