The Girders which span from column to column carries loading from the intermediate beam and also part of the seismic resisting member of the building. This video shows the design of girder using the spreadsheet. Staad does not completely give a detailed design of girder because there are many considerations especially Code provisions in earthquake. Thus, a spreadsheet is important to guide the designer. For example, the minimum NSCP width of girder 250mm is not one of the parameter in staad.
