Steel Purlin Design per AISC 360-16

How does ideCAD design steel purlins according to AISC 360-16?

Flexural Design and Combined Flexural and Compression Design

Stell purlin design strength is defined in consideration of combined forces.

• Steel Beam Design per AISC 360-16

• Design of Steel Columns for Combined Forces per AISC 360-16

When purlins are included in the analysis system, they are designed by considering the axial force and biaxial flexural moment. If the purlins are not included in the analysis system, the axial force is zero. So, it is designed with only flexural moments.
