In this tutorial, the Simulation fire condition over a RC beam(concrete+bar) in Abaqus-Thermal analysis- has been studied. The concrete beam is modeled as a three-dimensional solid part. The steel bars are modeled as three-dimensional solid parts. To consider heat transfer in the steel bars, using the solid part and element is necessary because the wire part and truss element can’t consider the heat transfer during the analysis. You can see a figure of the assembled parts below
To model concrete behavior under fire condition, the material should be appropriate and for that purpose the specific heat and conductivity depends on the temperature is used. For the steel bars specific heat and conductivity is used also. The heat transfer step with two hour time duration of the fire is selected. The three types of the heat transfer method is applied. The film condition or fire condition as a convection method with a amplitude to apply fire temperature is selected. The radiation is applied to the surfaces of the concrete beam. The conduction also is considered among the steel bars and concrete beam. The fixed boundary condition is assigned to the two ends of the beam and initial temperature to the whole of the model. The mesh should fine to obtain good results
After the simulation, all results such as nodal temperature, element temperature, increasing concrete beam temperature, distribution temperature in the steel bars, and … are available. You can some figures for the results below
