Analysis of Mechanics Characteristics of Prestressed Steel Beam in High Temperature (Fire) Condition

Abstract:

According to the requirements of fire science theory and structural fire resistance design, and the situation of possible disasters that may occur in the building based on practical project, this paper analyzes the mechanical characteristics of prestressed steel beam under high temperature (fire) circumstances. It puts forward how to consider the effects of parameters of different steel categories, the magnitude of prestress tension control forces and prestressed loss of steel cables on the structural bearing capacity in prestressed steel beam design, which can provide references for the fire resistance design of prestressed steel structures.
