SiF2024 - What fire rating is optimal for a nine-story steel-concrete composite building?

Mengying presents the cost-benefit methodology recommended within the NFPA Research Foundation project "Economic Impact of Fire: Cost and Impact of Fire Protection in Buildings" (www.nfpa.org/e....
One of the project's case studies is presented in detail: the evaluation of the optimum fire rating for a nine-story steel-concrete composite commercial building.
