文摘

Composite beams protected with 1 h FRR and subjected to a 1 h fire have damage in the connection during cooling Composite beams protected with 2 h FRR have no damage or failure when subjected to a 2 h design fire Consideration of slab continuity will improve the behavior of composite beams in fire conditions Mild steel reinforcement in the slab will improve the behavior of composite beams in fire conditions
