I have modeled a 70 m high preheater building on Staad. The base upto first story was concrete. Then upto to top it was steel flooring and steel everything. Due to the nature and slenderness of the building we used lateral bracing. I modeled them simentaneously and used the changed command to activate and deactivate bracing members and afterfinalizing the steel members added the concrete design in the last segment. All done through a single input file.
If you are trying to combine two or more models of the same structure, remeber two things. First origion should be same in all parts of models. No 2 number the frames/ elements in each model so that they donot overlap. For this purpose you can leave gaps between your numbering. It is okay with Staad. After completing geometry, property, material, loading assignmrnts. Simply open the any one file in Staad. Go to Input editor. Open the the other input files in Notepad or Wordpad and simply copy paste your data. This way, since the origion was same. you will get all your data in one piece. Save the file and return to dispaly window your full structure should be shown now. Select the whole structure joints, goto tools menu and click connect. This will delete any duplicate joints.
Hope this help. If you want further clarifications. Post it and I will try to reply. I am an structural engineer from Pakistan and have been using Staad for the last 14 years.
