Analyzing seismic behavior and micro-modeling of masonry walls using ABAQUS software

The occurrence of numerous earthquakes and the conducted geological research on the existing faults all prove that living in a seismically prone region. On the other hand, due to the lack of attention of the engineering community to save the construction, many buildings have been left in which the special preparations for earthquakes have not been considered. Since the gained experiences from past earthquakes show the high vulnerability of the masonry buildings, it is necessary to investigate the vulnerability of the existing masonry walls to identify the vulnerable points in the earthquakes and improve the seismic performance of the masonry buildings by a suitable solution. Taking into account the wide array of masonry building materials available worldwide, this article delves into an in-depth investigation of masonry buildings' seismic performance. It not only identifies their vulnerable points but also highlights potential points of rupture. Subsequently, we utilized ABAQUS software to create models and conduct a rigorous analysis of several masonry walls. The results of this study showed that the masonry walls could be rationally analyzed with suitable modeling by using the finite element method, and the behavior of the wall can be investigated under the applied loads.
