Fire Resistance of Steel Beam to Column End Plate Connections

The study describes numerical simulations that were conducted on a substructure of the steel building, namely a beam-to-column endplate connection. These simulations were made in order to know more about the behaviour of this connection before putting up and start experimental tests. The fire action is simulated by applying time-temperature curves on the studied structure. The model is advanced, taking into account for all types of nonlinearities, the computation being iterative. Two main fire cases were studied while the applied force was increasing on the structure.
