Deflection Change Analysis of Bending Steel Beam under High Temperature and Uniform Loads

Abstract:

In case a fire occurs in a steel structure building, materials properties and mechanical properties have undergone great changes, especially bending beam, its force complex than other members, charged with an important role in the structure, when the fire broke out the other members also prone to failure. This article refer to the document [1], the deflection change of bending steel beams subjected to fire are studied, analyzed its variation trend with the fire temperature, the accurate judgement of the stress state on the fire burning at different time can make the stress analysis more accurate and reasonable.
