Steel Purlin Design per AISC 360-16

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


  • Steel purlin design is made automatically according to AISC 360-16.

  • The user can change secondary steel purlin design settings.


Flexural Design and Combined Flexural and Compression Design

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

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.
