Unreinforced masonry walls and flange effect: a parametric study through block-based modeling

This study reported in this thesis shows the flange effect in unreinforced masonry walls subjected to in-plane loading. Previous studies showed the importance of capturing the in-plane behaviour of flanged masonry walls for seismic studies. A generative tool was developed using Dynamo and Abaqus Scripting Interface (ASI) to make a parametric model covering most cases of constructing the flange wall. The analysis was held using Finite Element Method through ABAQUS software and masonry wall was modelled through block-based modelling strategy. Large parametric study was carried out to investigate the effects of several parameters on the collapse load and failure type. The effect of aspect ratio, length of flange part, location of the main part, vertical applied load and the applied boundary condition are represented in this thesis.
