Design of Steel Shear Connections for Eccentricity as a Result of Secondary Bending Moment

Abstract

Shear connections develop a moment under the rotational demand imposed to them by the supported beam. For single-angle, double-angle, and tab to tubular column shear connections, this moment can be obtained through the equations derived from appropriate plastic yield line mechanisms. The primary application for the moment equations in the design of a connection is that the obtained moment can be used to estimate the load demand on the bolts and/or welds of the connection. This paper illustrated the moment equation method through various examples. Compared with the current empirical approaches in connection design, the proposed equation method is versatile and insightful.
