steel strength and member strength for a given fire resistance. The ACI Fire Code includes Tables stating the (1) minimum concrete cover for reinforcement in concrete floors and roof slabs, (2) minimum concrete cover for nonprestressed and prestressed flexural reinforcement in beams, and (3) minimum concrete cover for reinforcement in columns. spray-applied fire resistive material (SFRM) designed to provide fire resistive ratings for structural steel and concrete in commercial construction. Applied directly to deck, steel beams, columns or concrete surfaces, the outstanding value and proven fire resistive performance of BLAZE-SHIELD II make it an
I''m trying to attain beam ratings. Since there is more than one floor bearing on the steel, i cannot simply enclose the beams within the floor/ceiling assembly to attain the protection. I''m required to protect them individually. 18.104.22.168 Scantlings of steel ‘A’ Class divisions Where wedges are used to stiffen ‘A’ Class bulkheads the spacing should not exceed 760mm. Table showing the geometrical properties required when using steel stiffeners or beams spaced 760mm apart and without end connections.
