Example Description
This example uses a cantilever beam to test this model frame insertion point. In this model the frame insertion point is defined by a combination of a cardinal point and joint offsets.
This example uses a 12 inch wide by 18 inch deep section. The cardinal point is specified to be at the bottom left corner of the section (cardinal point location 1) and global Z direction joint offsets of +12 inches are specified at each end of the beam.
Two load cases are considered. The first load case has a 10 kip compressive load applied to the joint at the free end of the cantilever. The second load case applies the 10 kip compressive load to the free end of the frame object (not the joint).
The fixed end moments and the maximum beam moments are compared with independent hand calculated results for the two load cases.
Tested Features
- Frame cardinal point
- Joint offsets
