The present research work evaluates the ultimate shear capacity of a beam-to-beam moment connection comprising a 2-bolted clip-angle with a flange strip with 44 laboratory tests. The ultimate shear capacity of the 2BM connection was investigated by varying the clip-angle design parameters such as (i) thickness and (ii) aspect ratio (L/D). The governing failure modes observed in the 2BM connection are (i) tearing failure and (ii) shear local buckling based on the L/D ratio of the clip-angle. Following the conventional approach, an empirical shear strength equation for the chosen 2-bolted moment connection (2BM) is proposed (Method-1). In addition, a new design method is introduced (Method-2), and the increase in shear strength of the 2-bolted moment connection over the 2-bolted shear connection is evaluated with a rigidity factor. The shear performance of the 2BM connection is 2.37 times that of the 2BS connection due to adding a flange strip. Design factors for the Load and Resistance Factor Design (LRFD), Limit State Design (LSD), and Allowable Strength Design (ASD) methods are produced by conducting the reliability analysis on the experimental data.
