Abstract
This paper presents the results of a study to investigate the behavior of thin masonry domes under the action of gravity and lateral seismic loads. The finite element method of analysis is used to determine the reaction components for the support conditions specified, amd maximum stresses and deformations are presented. An analogous hemispherical concrete dome was selected for this initial study because its stress conditions were known for gravity loads. This was necessary for the development of a finite element model for use in a dome analysis. For our study, we chose the hemispherical dome and the shallow dome for comparison. Both domes have a span radius of 11.43 meters and a thickness of 127 millimeters. This compares with the classification of the masonry domes. It is the authors・hope that this study will help enhance the understanding of seismic behavior and the conservation of historical thin masonry domes.
