Burnout resistance based on the Duration of Heating Phase concept – Literature Review and Roadmap

Gernay, Thomas and McNamee, Robert LU (2024) In TVBB
Abstract
This study focuses on the fire behavior of structural members considering their response until the end of the fire event. The study reviews and discusses a framework for determining the burnout resistance (B) of structural members through the Duration of the Heating Phase concept (DHP). This framework complements the fire resistance rating (FRR) system by providing a rating that captures the sensitivity to delayed structural failure during the cooling phase. The report describes experimental and numerical studies on concrete, timber, and steel members, highlighting substantial differences between their fire resistance rating, based on evaluation during the heating phase, and their burnout resistance, based on evaluation under the heating...

This study focuses on the fire behavior of structural members considering their response until the end of the fire event.

This framework complements the fire resistance rating (FRR) system by providing a rating that captures the sensitivity to delayed structural failure during the cooling phase. The report describes experimental and numerical studies on concrete, timber, and steel members, highlighting substantial differences between their fire resistance rating, based on evaluation during the heating phase, and their burnout resistance, based on evaluation under the heating and cooling phases. With the burnout resistance as a complementary rating to fire resistance, a more holistic characterization of the safety and robustness of different structural solutions can be evaluated. (Less)
