Options for treatment of data

When the results are loaded intro PREFAB, they will be treated. There are two overall options for this:

1. Based on FEM-Design
2. New plastic distribution

Below is an example of data from FEM-Design, and how it's presented using Based on FEM-Design - with it's elastic compression zone variant. 

Based on FEM-Design

It keeps resultants like FEM-Design, and only smoothens the connection forces to one of the two:

1. Elastic - Simple linear variying compression zones.
2. Plastic - Simple constant value compression zones. 

New plastic distribution

It finds a new distribution for the model, based on the simple design capacity or plastic limit of edge-connections and trusses. It's important to note that the load distribution changes in such a way that the original FEM-Design model can only be considered as information about geometry, capacities and loads to PREFAB. 

There are two options to choose between: 

1. Full - PREFAB looks at the full model when determining the solution with the lowest utilization. 
2. Storey - PREFAB looks at one storey at a time, and finds the solution with the lowest utilization for that before continuing.

The Full option gives the best utlization, but the Storey option often gives the most intuitive solution.  

Add cover thickness to cut wall geometry

In the Display Model tab, a cover thickness can be added covers. It allows for the thickness + cover alignment. This will automatically create cutouts in the elements. Each cover can be set up individually. 

The effect of this is only represented if the elements are exported back to FEM-Design (.struxml) check this page on how to export. 

This short video shows you how to set the cover thickness and alignment. The Cover thickness button only controls if it's visualised in the 3D view or not. When the thickness is set, it will affect the export to .struxml if visualised or not.
