Seismic Behavior of Historical Royal Cenotaphs (Chhatris) in Gujarat, India During the 2001 Bhuj Earthquake
The state of Gujarat in western India has a rich architectural heritage, as evidenced by the abundance of historical monuments found to extend from Bhuj in the west to Ahmedabad in the east. A unique feature of the cultural heritage of Bhuj in particular are the cenotaphs (Chhatris) built during the 1700s under the Jadeja dynasty that ruled the region from 1540–1948. These cenotaphs are canopy-like structures, and are traditional symbols of Hindu architecture. Typically constructed out of local stone, they consist of an open simple structure on a raised platform, with a central dome or multiple domes supported by stone pillars. This paper presents the results of a study comprising the documentation, assessment, and restoration of historical royal cenotaphs following the 2001 Bhuj earthquake. Using SAP2000, a 3D finite element model of a representative cenotaph structure was first developed, based on approximate observed geometry and assumed material properties for the structure. A structural analysis was then carried out under the action of gravity and lateral (seismic) loads. The results are presented in terms of seismic base shears and expected displacement response behavior, while an assessment of the overall seismic safety and stability of the structure is also carried out.
