Splice Connection Design per AISC 360-16

How does ideCAD design Column/Beam splice connection according to AISC 360-16?

• Column/Beam splice connection design 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.

Connection Geometry

GEOMETRY CHECKS

Bolt Spacing at Flange

The distance between the centers of bolts is checked per AISC 360-16.

Horizontal Edge Distance at Flange

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 at Flange

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.

Bolt Spacing at Web

The distance between the centers of bolts is checked per AISC 360-16.

Horizontal Edge Distance at Web

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 at Web

STRENGTH CHECKS

Bolt Shear at Flange

The calculation is made using the Elastic method, one of the methods selected in the steel analysis settings tab. 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 Flange Plate

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

Bolt Bearing on Beam Flange

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

Flange Plate Tension Yield

The yield limit state of the connection plate subjected to tension is checked according to AISC 360-16.

Flange Plate Tension Rupture

The limit state of the flange plate tension rupture is checked according to AISC 360-16.

Flange Plate Block Shear

The block shear limit state is checked according to AISC 360-16. All block shear modes combined with tensile failure on one plane and shear failure on a perpendicular plane are checked according to AISC 360-16.

Beam Flange Block Shear

The block shear limit state is checked according to AISC 360-16. All block shear modes combined with tensile failure on one plane and shear failure on a perpendicular plane are checked according to AISC 360-16.

Flange Plate Compression Yield

The yield limit state of the connection plate subjected to compression is checked according to AISC 360-16.

Bolt Shear at Web

The shear limit state of end plate bolts is checked according to AISC 360-16.

Bolt Bearing on Web 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.

Bolt Bearing on Beam Web

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.

Web 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.

Web 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.

Beam 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.

Web Plate Block Shear

The block shear limit state is checked according to AISC 360-16. All block shear modes combined with tensile failure on one plane and shear failure on a perpendicular plane are checked according to AISC 360-16.
