Consteel 14 is a powerful analysis and design software for structural engineers. Watch our video how to get started with Consteel.
Contents
- Set analysis parameters
- Perform first and second order analysis
- Perform buckling analysis
- Analysis results in graphics and in tables
- Results: deformation, internal forces, reactions
Introduction
As you may already know, you can check the max, min and min-max envelope diagrams for (first and second order) analysis results in Consteel. But you can also create your own envelope figures…
How it works
By default the envelope figures can be requested for ULS and SLS combinations. These default options will use the results of all of the calculated ULS or SLS load combinations:
To create your own envelope figures:
If you choose the Define envelope figure… option from the load combinations dropdown menu of the analysis tab, you will get the User defined envelopedialog:
gateIntroduction
In case of a model with a lot of load cases (wind in different directions, with and without internal pressure, snow,seismic etc.), hundreds of load combinations can be generated acc. to EC but many of these combinations are irrelevant. Running an Analysis on all of the load combinations can take a lot of time, that could be saved, if the relevant load combinations are calculated only.
How to do that
- To find the relevant load combinations and save calculation time: At first perform only elastic first order analysis and global checks based on that. Even first order calculation can take much time if there are non-linear elements (practically tension-only rods) in the model. It is possible to temporarily change the non-linear elements to linear ones in order to let Consteel calculate the load combination analysis results with superposition of the load cases which is much quicker than calculation with non-linear elements.
- Under the Global checks tab, on the results table, selection of the load combinations with significant utilization can be done. (As on all tables in Consteel, multiple selection of different load combinations can be performed easily using Ctrl+select, or Shift+select features of Windows) With a right click on the selected combinations, use Select only these combination for the Analysis function to apply your choice to the next run.
