Abstract Tension and compression force-deformation data obtained from laboratory tests of angle segments are used to generate moment-rotation curves for bolted double framing angle connections. These force-deformation and moment-rotation curves are analytically described by a four parameter formula which provides the basis for the analytical connection model. This connection model consists of a rigid bar and nonlinear springs representing the angle segments in either tension or compression. Design curves giving the four parameters of the moment-rotation curves are generated. These parameters are primarily a function of the angle thickness, gage length of the angle legs in flexure and the number of bolts in the connection. Comparison of these derived moment-rotation curves are made with published results of full scale tests.
