WebObjective: Two kinds of fire-resistant steel with different Nb content (Nb-free and 0.03 wt.%) were prepared for studying the effects of Nb addition on the elevated-temperature strength of fire-resistant steel. Methods: Two stages of heat treatment were carried out on the steels to obtain different microstructures. Typical microstructures, dislocation, and … WebThe required equivalent thickness of an assembly constructed of units made with expanded shale (80% by volume), and calcareous sand (20% by volume), to meet a 3-hour fire resistance rating is determined as follows. From Table 1: T1 for expanded shale (3 hr rating) = 4.4 in. (112 mm) T2 for calcareous sand (3 hr rating) = 5.3 in. (135 mm)
WebJul 26, 2024 · Nowadays, there are different solutions available for the fire protection of steel structures. The following systems are commonly applied: Box protection of fire protective boards Horizontal and vertical … WebStandards for the fire resistance of steel are set by two main pieces of legislation: Fire safety: Approved Document B, which is generally accepted as the main set of regulations for passive fire protection and BS 9999 which are the requirements set by the British Standards Institution for fire safety in the design, management and use of buildings.
WebTherefore, the fire resistance can be improved by adding prestressing bars, increasing the concrete strength, and increasing the thickness of the protective layer in the design. Finally, a fitting equation for fire resistance of the prestressed concrete T-beams based on the finite element model calculation data was created.
