Seismic Assessment and Fortification Essentials (SAFE) is a practical guidebook that provides a structured framework for the seismic assessment, structural audit, and retrofitting of existing buildings. It bridges the gap between codal requirements and field implementation, covering condition assessment, structural evaluation, and strengthening techniques such as jacketing, shear walls, bracing, base isolation, and post-installed systems. Focused on the Indian context, the handbook promotes proactive risk mitigation and supports the development of safer, more resilient, and earthquake-resistant structures.
