| dc.description.abstract | Seismic evaluation helps to identify structural and non-structural vulnerabilities in existing buildings. This includes weaknesses in the building's design, construction materials or foundation, which might make it susceptible to earthquake damage. Older buildings were often constructed using old codes that may not be as stringent as modern ones. Evaluating these buildings against current seismic design standards helps to determine if they meet contemporary safety requirements. The aim of this study is assessing how ductility class, flexural and shear hinge length, impact on the seismic performance of an existing reinforced concrete frame structure in a seismic zone three setting as per EN 1998-3:2004. The seismic performance evaluation of the proposed structure is carried out by using nonlinear static procedure (NSP) or pushover analysis as per EN1998-3:2004 guidelines. Seismo-structure v-2023 program is used for pushover analysis by providing user-defined nonlinear hinge properties. The study's findings suggest that the length of flexural and shear hinges and the chosen ductility class are important factors to consider when designing earthquake-resistant structures as they have a direct impact on base shear and inelastic displacement capacity. | |
