Unstiffened Seated Connection Design per AISC 360-16

How does ideCAD design unstiffened seated connection according to AISC 360-16?

Unstiffened seated 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 states of single plate web yielding, web crippling and weld strength are checked automatically.

Connection Geometry

Geometry Checks

Weld Size

The minimum size of fillet welds is checked according to AISC 360-16 Table J2.4
