Behaviour of flush end-plate composite connections with unbalanced moment and variable shear/moment ratios—I. Experimental behaviour

Abstract A series of seven end-plate beam-to-column connection tests is reported; these include one pure steel connection and six composite connections. The main variables investigated are the degrees of unbalanced moment and the shear/moment ratio. Comprehensive instrumentation has been used to monitor: beam strains, column strains, rebar strains and bolt forces as well as member and connection deformations. This comprehensive monitoring permits a full understanding of the behaviour of this kind of connection. In addition, the large number of recorded variables provides data for the detailed validation of numerical analysis methods.
