ABSTRACT
India is susceptible to strong earthquakes and the vulnerable structures increase the disaster risk. Earthquake engineering have its foundation in dynamics which got developed as the sub-domain of mathematics and physics. The dynamics has been instrumental in understanding the response of structures to seismic excitations. It is necessary to know the background of numerical procedures for accuracy in analysis of buildings. The different methods for seismic analysis and design are compared to get the performance. In this paper, a fifteen storey RC building in seismic zone-IV is designed with IS, US and CEN codes. The performance is verified using ASCE41 and TEC07 threshold limits following the performance-based design procedure. It is observed that the SPD and code provisions provide LS-CP performance level while the resilience could not be quantified in terms of recovery indices i.e., time and cost optimization based on functional needs of the building. Also, the identification of seismic hazards, assessment of vulnerabilities and implications of exposure conditions are required as part of a disaster risk reduction strategy. The software design cannot give resilient structures directly and a resilience prescription is necessary in the building byelaws for generating local and global seismic resilience in India.
