Simulating the Compounding Effect of Freeze-Thaw Cycles on the Durability and Seismic Performance of Masonry Buildings

The frost deterioration caused by freeze-thaw cycles (FTC) is of great concern in masonry buildings due to its detrimental effect on durability and long-term seismic performance. Recent findings reveal a substantial reduction in mechanical properties of masonry (e.g., compressive strength) when exposed to
FTC. This material damage weakens the seismic capacity of masonry walls, increasing the vulnerability of existing masonry buildings and cultural heritage. Therefore, the proposed research program aims to simulate the seismic behavior of masonry buildings considering the deterioration and aging caused by
FTC using a novel computational approach based on the finite-discrete element method (FDEM). The outcomes of this project will fill the knowledge gap in the literature regarding the influence of frost deterioration on seismic structural performance and capacity. Furthermore, better preservation plans will
be implemented for existing buildings susceptible to changing climate conditions and seismic actions.
