Probabilistic Calibration of Particle – Based Masonry Wall
Title of Research:
Probabilistic Calibration of Particle – Based Masonry Wall
Abstract:
Experimental observations from lab testing shows that the interface between the mortar and the bricks has an important influence on the behavior a masonry wall. This research aims to use the discrete element method (DEM) for modeling a rehabilitated masonry wall. The model will be calibrated using the experimental observations to reproduce the mortar-brick interface subjected to compression and extension. Results will provide estimates likely scenarios of mortar-brick fracturing. PFC2D by ITASCA is the software used in this study.
