16、16-07FOREWORDFire resistance of building elements is an important consideration inbuilding design. While structural design considerations for concrete andmasonry at ambient temperature conditions are addressed by ACI 318Mand ACI 530/ASCE 5/TMS 402, respectively, these codes do not considerthe impact

17、 of fire on concrete and masonry construction. This standardcontains design and analytical procedures for determining the fire resistanceof concrete and masonry members and building assemblies. Wheredifferences occur in specific design requirements between this standardand the aforementioned codes,
