Comparative assessment of finite element macro-modelling approaches for seismic analysis of non-engineered masonry constructions

Abstract All around the world, non-engineered masonry constructions (NECs) typically have high vulnerability to seismic ground motion, resulting in heavy damage and severe casualties after earthquakes. Even though a number of computational strategies been developed for analysis unreinforced structures, few studies focussed on NECs located developing countries. In this paper, different modelling options finite element buildings are investigated. The goal study was identify option with best trade-off between burden accuracy results, view risk assessment at regional scale. Based experimental behaviour single-storey structure representative Indian buildings, output response refined 3D models ANSYS compared that simplified model based 2D, nonlinear, layered shell elements SAP2000. numerical-experimental comparison carried out under incremental static lateral loading, whereas nonlinear time history performed investigate dynamic performance case-study structure. Analysis results show can be computationally efficient both analyses, particularly case force-based approaches design base isolation systems aimed large-scale mitigation NECs.
