Q690 HW CARBON STEEL H BEAM is noncombustible, it is not fire resistant. When the temperature reaches 600 °C, the steel will lose most of its strength and stiffness. Therefore, once a fire occurs in a steel building, the structure is easy to be damaged or even collapsed [1]. The changes in the mechanical properties of structural steel due to fire are mainly reflected in two aspects: the influence during fire and that after fire. When the steel structure is exposed to fire, the temperature of the structural steel is relatively high.
