Study on the fire resistance performance of integrated steel beam with fire protection and decoration under fire

Abstract

Abstract: In order to study the temperature field and bearing capacity of steel beams with integrated fire protection and decoration structure under fire, the fire resistance performance of steel beams with different cross- sectional sizes and different fire resistance limits was studied through an analysis model based on ANSYS software, and a simplified formula for calculating the bearing capacity of steel beams were given. The formula calculation results are in good agreement with the finite element results.

Key words: , steel beams with integrated fire protection and decoration structure, fire resistance, finite element
