In this tutorial, the Simulation full three Dimensional fire analysis of a Reinforced concrete beam in Abaqus-Sequential Coupling Technique- has been investigated. The concrete beam is modeled as a three-dimensional solid part,. The longitudal bar and strips are modeled as three-dimensional solid part. You can see a figure of the assembled parts below
In the thermal simulation, we have three ways to transfer the heat and energy
Conduction occurs when atoms or molecules interact with each other. It happens most frequently in solids, but also occurs in liquids and gases
Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water
Radiation heat transfer is a process where heat waves are emitted that may be absorbed, reflected, or transmitted through a colder body. The Sun heats the earth by electromagnetic waves. Hot bodies emit heat waves
In this tutorial, we used the two first methods to define the fire effect. In the first model, the thermal properties of concrete and steel reinforcement are used to consider the thermal effect, and the heat transfer step is selected to report the nodal temperature. The fire is applied as a convection method by using a file coefficient and an amplitude. The second model is considered as a mechanical analysis by using a general static step that considers the nodal temperature from model one to change it to the stress in the structure model. The proper boundary conditions are assigned to all parts of both models. The proper mesh can help us to get the better results
After the simulation of both thermal and structural, the results would be available. You can see some figures for the results below such as temperature, stress, strain, displacement
