Example Description
This example tests this model for various types of loading on a frame element with its local 2 and 3 axes not parallel to the global axes. A W12X106 cantilever beam is used with the local 2 axis rotated 30 degrees from the global Z axis as shown in the figure below. The free end displacements in the global Y and Z directions are compared with independent hand calculations. The W12X106 section properties are read from the SECTIONS8.pro section database provided with this model.
Important Note: Only bending deformations are considered in the analysis. In this model shear deformations are ignored by setting the property modification factor for the shear area to zero.
Tested Features
- Frame local axes rotated from global axes
- Use of AISC sections
