Bridges, buildings, dams, and pipelines are just a few examples of the complex engineering systems that sustain a society's economic stability and quality of life. These systems’ proper inspection, monitoring, and maintenance become more crucial as they get older and degrade. In such case the probability of occurrence of damage is high. The early identification of structural damage is vital to avoid structural failure in case of extreme loading conditions, which undetected can result in catastrophic conditions. Hence, there is a need for assessment and study of behavior of the damaged structural elements or structures as whole in order to increase the safety and serviceability of any structure and to maintain structural integrity for longer period of time. This study aims to investigate the effect of damage location and severity in beams and columns of a multistory steel structure. Different damage scenarios, i.e., reduction in cross sectional area, stiffness, and Young’s modulus are considered to introduce damage at different locations in beams and columns. In order to predict the critical location and severity of damage, modal analysis is carried out to find the dynamic behavior of damaged structures. The natural frequency and time periods are considered as dynamic response parameters. Further, lateral load analysis, i.e., equivalent static method is performed as per IS 1893 (Part-1): 2016 code provisions. From the results, it has been observed that there is a change in the natural frequency, member forces, and lateral displacements of the structural system with the introduction of damage of certain severity and at particular location.
