GEOMETRY CHECKS

Horizontal Edge Distance

The distance from the center of the hole to the edge of the connected part in the horizontal direction is checked per AISC 360-16.

Vertical Edge Distance

The distance from the center of the hole to the edge of the connected part in the vertical direction is checked per AISC 360-16.

Weld Size

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

STRENGTH CHECKS

Bolt Tension at Support

Bolt tensile strength is checked due to axial force and bending moment interaction effect.

End Plate Thickness

The required end plate thickness, t_p, for four bolts stiffened end plate connection is checked according to AISC 358-16 §6.8

End Plate Shear Yield

The shear strength of connecting elements in shear is the minimum value obtained according to the limit states of shear yielding and shear rupture. Shear yielding is checked according to AISC 360-16.

End Plate Shear Rupture

The shear strength of connecting elements in shear is the minimum value obtained according to the limit states of shear yielding and shear rupture. Shear rupture is checked according to AISC 360-16.

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.

Bolt Bearing on End Plate

Bearing strength limit states of the connection plate that are “shear tear out” and “ovalization of bolt hole” for both end and inner bolts are checked according to AISC 360-16.

Weld Size

The required end weld size is checked according to AISC DG-4.

Weld Strength

The required end weld strength is checked according to AISC DG-4.
