Behaviour of composite haunched beam connection

This paper is concerned with the behaviour of steel–concrete composite haunch connections. Experiments were carried out to investigate the moment-rotation characteristics and ultimate moment capacity of these connections. Details of the experiments giving information on test specimens, instrumentation, test set-up and test procedures are described. Results obtained for connection moment capacity, rotation capacity and failure modes are presented. It is found that through proper design and detailing, these connections display the characteristics of a rigid connection.
