ABSTRACT
Using the test results, a parametric model was developed to predict the complete non-linear static moment-rotation behavior of the connections. The model offers reasonable predictions of the H-+ response of the connections; however, for the stiffest connections tested with each beam size, it underestimates the moments developed at the larger rotations. Until additional data are available and further refinements to the model are possible, it is recommended that the expression reported herein be confined to the estimation of H-+ curves for connections in which the thickness of the flange angles does not exceed appreciably the thickness of the flange of the supported beam.
