How does ideCAD design end plate shear connection according to AISC 360-16?


  • End plate shear connection limit states and geometry checks are done automatically according to AISC 360-16.

  • The block shear limit state is checked automatically according to AISC 360-16.

  • Limit state checks are made automatically according to AISC 360-16.

Strength Checks

Bolt Shear at Support

The calculation is made using the Elastic method, one of the methods selected in the steel analysis settings tab. For the details of this check, AISC Manual 14th 7-8 is used as a reference.

In this check, the operation is performed on half of the symmetry axis and is calculated to form a force pair with the required force.
