Low-ductility braced steel frames are widely used in moderate seismic regions of North America. A research project has been initiated to examine the possible benefits of considering the moment resistance of beam-to-column connections in the gravity load-carrying system to provide such braced frame building structures with minimum dependable lateral reserve capacity. Beam-to-column moment connections are constructed using top and seat angles acting together with beam web clip angles. A first test program has been developed to characterize the inelastic behavior of individual angles subjected to monotonic and cyclic demands. Test results are presented to illustrate the influence of several parameters, including the angle geometry and the loading sequence. A second test program has been undertaken to examine the cyclic inelastic response of the proposed beam-to-column joints. The test program is described and joint rotation capacity predictions based on individual angle test results are presented and discussed.
