Beam-to-column connections have been shown to have great influence on structural behavior at ambient and elevated temperatures. When steel-framed structures are subjected to fire, the load-bearing capacity is decreased and the behavior of the joints is of particular concern. In this paper, the behavior of a semi-rigid Khorjini connection is studied at elevated temperatures. Four experimental tests are carried out on this kind of connection at elevated temperatures, and the results are presented as temperature–rotation and moment–rotation curves. Then, finite-element models are developed and compared with the experimental tests. Good agreement was achieved between the model and experiment, confirming that the finite-element method is capable of predicting the behavior of these connections at elevated temperatures.
