Enhancement of Seismic Resilience in Buildings: A Proposed Appendix to the Iranian National Seismic Code

This paper presents a framework for enhancing building seismic resilience through a proposed appendix to the Iranian National Building Code (Standard ۲۸۰۰). The framework introduces three primary strategies: repairable structural systems, enhanced design requirements, and consequence-based design with lifecycle risk management. Analytical and experimental evidence support the effectiveness of these strategies in achieving multiple performance objectives, including minimized post-earthquake recovery time, reduced repair costs, and improved building performance beyond current code requirements. The proposed methodology integrates technical, economic, and social considerations through a multi-criteria decision-making approach, supported by lifecycle cost analysis and performance-based engineering principles. As the concept of seismic resiliency will be the first time to be addressed in the code, the main challenge was selecting the main pillars that should be considered.  The proposed guidelines aim to minimize post-earthquake recovery time, reduce repair costs, and improve overall building performance beyond current code requirements of the Standard ۲۸۰۰. This approach integrates technical, economic, and social considerations to achieve optimal seismic resilience.
