Bolted Stiffened and Unstiffened End Plate Connections

There are prequalification limits for moment connections that have been satisfactorily tested. All end-plate moment connection configurations should satisfy these beam and column limitations. Beam and column limitations are given in AISC 358-16 6.3. ideCAD Structural automatically checks Beam and column limitations.

Plastic hinges cause inelastic bending deformations in the joining beam and column panel zones. Therefore, panel zones should conform to the requirements of the AISC Seismic Provisions. In addition, Column-beam moment ratios should conform to the requirements of the AISC Seismic Provisions.
