Has anyone ever modeled a tapered beam/col frame for a metal bldg? The nonprismatic beam definition starts and ends with a wide flange section, not sure if this accurate, aren't they welded plate girders?
There's an ETABS FAQ on engineered tapered section on the CSI website under the Support section. Use the "Add" I/Wide flange to use plate girders instead of using standard steel shape from a library
