Abstract

This paper presents a finite element analysis procedure developed to study the behavior of a flexible end-plate connection between steel beams and a column at elevated temperatures and generates temperature-rotation diagrams that describe the behavior of the connection. The analysis used a highly detailed three dimensional finite element model that is created using the commercial ABAQUS software. The steel connection properties are selected in a way that reflects commonly used connections in steel framed buildings. The results of the finite element model are calibrated and compared to the results of experimental fire tests conducted on similar connections. The results show that the predicted behavior of the joints is in a good agreement with actual behavior of the joints. A regression model is developed to describe the behavior of flexible end-plate joints in fire.
