This study quantifies the seismic vulnerability of typical three storied class room building located in SriLanka. A significant feature of this reinforced concrete frame building is that this was not designed for seismic effects. Besides, there are some infill brick walls also.
A methodology given in “Guidelines for Seismic Performance Assessment of Buildings”( ATC-58 ) was followed as it was expected to study consequences of earthquake. As per ATC-58, intensity based assessment was considered for Hazard Analysis while the Structural Analysis was carried out to obtain engineering demand parameters (EDP) such as story drift and story acceleration. Besides, a Damage Analysis was carried out not only for structural members but also for non-structural members. Pushover analysis was done in order to define damage states of the structural while Loss Analysis was carried out to quantify the direct economic loss.
