Limit State Tables

The AISC 360-16 Specification has significant changes to Chapter K in HSS connection design. To help designers navigate these changes, we created Limit State Tables available for free download. The tables step through limit state checks required for various HSS connection configurations resisting shear, axial, and moment, and include equations for both AISC 360-10 and 360-16 Specifications.
