Damage Assessment of Reinforced Concrete-Framed Building Considering Multiple Demand Parameters in Indian Codal Provisions
This paper investigated multi-objective seismic damage assessment procedure. Primarily, it estimates damage index (DI) of reinforced concrete-framed residential buildings situated in seismic zone V as per IS-1893-2016 (0.36 g) in India. Three-dimensional DI has been estimated for a four-storey building by Park–Ang method. With the increase in the storey number, calculation of Park–Ang DI becomes tedious and more time-consuming procedure; therefore, this method is not suitable for large-scale damage investigation. To avoid the complexity, a simplified method has been proposed to estimate global damage index (GDI) of buildings easily. For this purpose, a four-storey residential building having plan aspect ratio 0.5, 0.75 and 1 has been analysed. In this study, the most influential parameters such as inter-storey drift, joint rotation and peak roof displacement have been combined to estimate GDI of structures directly. Based on this study, it has been observed that 0.893 times ground-storey DI (i.e. local DI) estimates similar Park–Ang GDI for a four-storey building. In this study, it has been observed that ground floor experiences maximum damage and top floor experiences least damage for all cases. The proposed approach effectively estimates reliable GDI that is useful for small- to large-scale damage assessment of buildings.
