Abstract
An effective medium approach is applied to elasto-plastic masonry to facilitate numerical modeling of the fourteen century old Hagia Sophia in Istanbul, Turkey. The analysis is treated in two distinct stages: quasi-static to account for the deformations incurred by the structure under gravitational loading during its construction phase, and dynamic to account for the response to numerous seismic excitations. Both historical and physical evidence suggest that the mortars employed throughout the Hagia Sophia were highly compliant on the construction time scale; recent chemical analysis of the mortars appears to confirm that they may not have had time to fully cure before the structure's construction was completed. The resulting highly compliant initial behavior of the masonries is modeled within an effective medium elasto-plasticity framework which is demonstrated here as capable of matching the existing magnitude and pattern of deformations in the structure. With the eventual curing of the mortar, the properties of the masonries throughout the structure became significantly stronger; this is taken into account in modeling the seismic response of the structure to a number of earthquake excitations. Specifically, a hardening elastoplastic behavior with increased strength is used to explore the initiation of partial failure mechanisms in the structure under strong seismic loading.
