CSI SAFE Models

AEC | BOLT Building Design Suite enables user to create CSI SAFE models of each story easily.
If there is a load transfer on the floor to be exported, run tributary analysis first.
In this section, we will export each floor to CSI SAFE and after analysis, we will import results back to AEC | BOLT Building Design Suite. Let’s start with the 7th floor.
Go to Analysis → CSI SAFE → 7th Floor
If you haven’t draw design strips;
Click Design Strip and draw directions
If you draw one direction line, the second direction line perpendicular to the first one will be automatically drawn. Directions will be assigned to layers automatically as shown below.
Once you draw direction you can use the same directions for each story by clicking yes for the warning below.
Enter Design Strip Spacing
Select Safe Design Rebar from the spreadsheet
Enter top&bottom clear cover
Select rebar material
Set Generate Columns Above True
Set Generate Shear Walls Above True
Set Foundation Wall Aboves False
Enter Modulus of rupture coefficient, k
Click update button
Click Export SAFE (.f2k) File and save the file
Creating export file is successfully completed if you see log.txt as in below.
Open SAFE and import .f2k file of the 7th floor as shown below.
After SAFE analysis is finished, create .f2k file of the analyzed model;
Go to File → Export Model → SAFE .f2k
Select tables as shown above
Save the file
Go to AEC | BOLT Building Design Suite
Click Import Safe Results
Select the file
You imported the results successfully if UI_Compare is as below.
Created “.f2k” files are also uploaded to AEC|BOLT BIM Cloud and are accessible only for users who are added to the project.
Now repeat the process for the remaining stories. You do not have to export both 5th and 6th floor, only one 6th floor export is enough because they are similar stories.
Foundation
The foundation model needs extra parameters to be set before exporting to CSI SAFE.
You must select which foundation objects will be exported.
Click Select Foundation Objects button to select the foundation objects as illustrated on the right.
Select all the objects
Select the analysis source
You must choose the source of the loads to be transferred to the foundation.
Set generate rigid zones as true
Enter design strip spacing
Select design rebar for CSI SAFE
Enter clear cover top&bottom
Set generate Column Aboves/ Shear Wall Aboves/ Foundation Wall Aboves as true
Enter modulus of rupture value
Enter spring mesh size in X&Y directions
Enter spring’s k values in X&Y directions
Update the project to cloud
The remaining steps are the same as exporting a floor model to CSI SAFE.
