STATSUB (PRELOAD) in Linear Static Analysis
Hello,
I'm having difficulty using the STATSUB (PRELOAD) option within my linear static load case. I would like to use an applied force preload to a bushing element in the attached .fem file. The sample distributed load is equal and opposite to the preload, which should result in a no-deformation condition.
The four load cases in the sample model are as follows:
- combined load: LOADADD of the preload and distributed load. This should result in a balanced zero-deflection result. Results are as expected
- preload: linear static load case with the preload force assigned to the "LOAD." This should result in a 0.25" extension of the bushing element. Results are as expected.
- STATSUB (PRELOAD): references "preload" case under STATSUB (PRELOAD) with distributed load assigned under "LOAD." This should result in a balanced zero-deflection result, but looks equivalent to load case 4.
- distributed load: distributed load assigned under "LOAD." Preload is not applied in this case. This should result in a 0.25" compression of the bushing element. Results are as expected.
Please help me to understand why load case 3 is not behaving the same as load case 1.
Thank you,
Mandy

Hello,
STATSUB(PRELOAD) will only include the effects of preloading as a weakening or a stiffening of the structure and will not transfer the stresses, displacements.
