Can I combine two models in STAAD Foundation Advanced ?
Here are a couple of scenarios you may encounter
If you have created these foundation models in STAAD Foundation Advanced ( SFA ) itself, then you can export these models individually to excel spreadsheets using the option “Export to Spreadsheet”. One you have the two excel files, you can copy the data from one excel to the other using copy and paste. Before you do that you must ensure that there is no overlap between the items like Nodes, Load Cases, Load Combinations etc. If there is, please renumber these items carefully before copying. For example if you are trying to combine two models with isolated footings, you would have a spreadsheet as shown next for each model after the export. You would need to carefully check the data on each of the sheets as marked below and copy the data to the appropriate locations to create one single excel file containing data for both models.
Once the data is copied, you can create a new STAAD Foundation Advanced model by importing the data from the combined excel file using the option Import Spreadsheet.
Alternately if you have the superstructure for both models analyzed in STAAD.Pro and you would like to create a single SFA model containing foundations for both, it is much easier to merge the STAAD.Pro models into one single file first.
