CFVR0806 - Combination module test with LINK10 elements

Example to check the combinations utility with LINK10 elements

This example checks the functionality of the combinations module with LINK 1 elements.

The model is a simple 60º X shaped model without the lower right beam. Each beam has different real constants and material properties, which do not represent a physical problem.
The load cases are:

  • Load Step 2, Sub Step 2: Horizontal load of 15 N (left direction) on the center node (10).
  • Load Step 5, Sub Step 5: Vertical load of 10 N (downwards) on the center node (10).
  • Load Step 10, Sub Step 10: Horizontal load of 25 N (right direction) on the center node (10).
No Civil materials or beam properties have been used in this example, only ANSYS results will be checked.

The targets for the combinations are:
  • Target 2: FX in BEAMS (ABS value)
  • Target 5: S DIR in BEAMS (Maximum value)
  • Target 10: EPEL DIR in BEAMS (Minimum value)

The combination rule defined is:
  • Combination rule 18: SELEC CFV - [(2.0 or 3.0)*H1, (1.0 or 2.0)*H2]

Element types used in the model: LINK10

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example can be launched on an educational license.
