| 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. |
