Evaluation Of The Seismic Vulnerability of the “Ancien Hôpital De Sion” Using Applied Element Modelling (AEM) and Local Mechanism Analysis
The evaluation of the seismic vulnerability of monumental buildings is a difficult task and presents significantly higher level of complexity if compared to the case of new or current existing structures. This is due to the inherent uncertainty characterizing ancient buildings, regarding structural characteristics and constructive techniques, material properties, damages due to past actions, which should be properly handled in their seismic assessment.
Unreinforced masonry (URM) structures have shown to be susceptible to significant damage during strong earthquakes. Vulnerability assessment of URM buildings is needed so that appropriate mitigation strategies can be implemented. The existing Canadian practice consists of rapid seismic screening of buildings to assign priorities for further and more refined assessments, followed by refined analysis of individual critical buildings.
Numerical Simulation of Polypropylene and Fiber Reinforced Polymer Composite Retrofitted Masonry Walls
In this study, an attempt is made to numerically simulate the behavior of Fiber Reinforced Polymer (FRP) and Polypropylene (PP) band composite using the Applied Element Method (AEM). Both of these materials have their own unique properties. FRP is used to increase the strength, whereas PP-band is used to increase the deformation capacity and energy dissipation capacity of masonry wall system.
