Stability Analysis of Single-Plate Shear Connections and Double-Coped Beams [N54]

Part 10 of the AISC 14th Edition Steel Construction Manual provides two equations for evaluating the lateral stability of single-plate shear connections and double-coped beams. Equation 10-6 evaluates the lateral torsional buckling capacity of single-plate shear connections and double-coped beams. Equation 10-7 evaluates the effect of lap eccentricity in single-plate shear connections. When required by these checks, a stabilizer plate can be used to provide lateral stability. This presentation provides discussion regarding the assumptions made in the derivation of the equations, and also provides insight into the application of the equations. Complete design examples are provided as reinforcement to the discussion.
