GeniE Example A9: Tension/Compression analysis

GeniE gives you the possibility to run a tension/compression analysis. A brief explanation on how to do

this in GeniE follows below. For a more detailed explanation and examples, see the tension/compression

manual in your Sestra installation. Note that Sestra D8.5-02 or a later version is required.

To run a tension/compression analysis you need to set the

beam type of the truss elements you want to analyse to

Truss Tension Only or Truss Compression Only.

To create a tension/compression analysis you need to check the Tension/Compression Analysis checkbox

as shown in the illustration.

It’s not possible to run a

tension/compression analysis with

a Wave Load Activity.

Before running the

analysis you need to

specify which loadcases

that should be run as

tension/compression. The

remaining loadcases will

be run as a linear structure

analysis.

Note that the loadcases

you include for

tension/compression

need to be the last in

the FEM loadcase

number sequence of the

analysis.

After executing the Tension/Compression analysis you can look at the deformations

and the G-Stress sigxx.

Beam forces are not available for truss elements.

For the test models LC1 and LC3 are identical, and so are LC2 and LC4.

Note the changes in results, since only LC3 and LC4 are executed as Tension/Compression loadcases.
