fire analysis of a composite beam(RC concrete slab+ steel beam)under bending load in Abaqus

In this tutorial, the fire analysis of a composite beam (RC concrete slab+ steel beam) under bending load in Abaqus has been done. The concrete slab is modeled as a three-dimensional solid part. The steel reinforcements are modeled as wire parts. The steel beam is modeled as a three-dimensional solid part, and a rigid body to apply load is used also. You can see a figure of the assembled parts below

Steel–concrete composite beams are often employed in office and industrial buildings or bridges and viaducts for fast and economic erection. Most usually they comprise a steel girder and a reinforced concrete slab interconnected by shear connectors (fasteners). The number of shear connectors largely determines whether the composite cross-section behaves as compact or partially connected. In any case, the deformation of the beam causes some relative tangential displacement (slip) between the steel girder and the concrete slab. While usually being very small, slip can have a substantial effect on the overall ductility of the beam, which indicates that it should be taken into account in the analysis. The issue that plays an important role in the concrete and composite steel–concrete beams response due to fire is the effect of moisture transport on the temperature and stress distribution histories in the concrete part of the cross-section. In the composite beam context discussed here, we are particularly interested in assessing these effects quantitatively

To model the fire analysis, first fire simulation through a heat transfer model is considered and the nodal temperatures are extracted from the model as an input for the structural model. In the second stage, the static model is performed bending is applied to the top surface of the concrete slab, and the fire results are implied as the initial situation

After the simulation of fire and static analysis, all results like stress, strain, temperature, displacement, and others are available. You can see some figures for the results below
