Discrete Element Modeling of Stone Masonry Walls With Varying Core Conditions: Prince of Wales Fort Case Study

Stone masonry walls with rubble cores can transition from stability to instability as cohesion between stones decreases, according to discrete element modeling (DEM) using the non-smooth contact dynamics method. This study highlights that grouting the core could serve as an effective conservation strategy for deteriorating fortifications like the Prince of Wales Fort in Churchill, Manitoba. The research employed DEM simulations to analyze the failure mechanisms of the fort's walls, which have suffered significant degradation due to harsh weather conditions. By altering the cohesion parameters in the model, the study demonstrated how the structural integrity of the rubble core could be compromised, offering insights into preventative conservation methods for similar historic sites.
