This authoritative book summarizes the latest knowledge on performance-based approaches to the fire safety engineering of structures. Going beyond codes of practice, it addresses issues that have become more important in recent years, including the integrity of fire-resistant compartmentation, the progressive collapse of structures in fire and provisions for connection robustness, and accurate information on material properties at high temperatures. Written by core members of the COST C26 working group on fire resistance, it explains how to use advanced fire engineering design to improve structural safety and reduce construction costs.
