Abstract

This contribution deals with the fire performance of external semi-rigid composite joints. First, the design principles of two newly developed joints are explained. Four fire tests were carried out to investigate the fire performance of the new joints. To study local phenomena in the joint, a three-dimensional numerical model was established with the Finite Element code Abaqus for one joint type. The data obtained from the fire tests were used to validate the model. It is shown that the model is suitable to predict the fire performance of the chosen external semi-rigid composite joint. Thus, parametric studies were conducted to extend the parameter set of the fire tests. Based on the results of the numerical studies, the paper concludes with recommendations for the design of the developed composite joints.
