BASEPLT9 DescriptionBASEPLT9 is a spreadsheet program written in MS-Excel for the purpose of analysis of steel column base plates. Specifically, wide flange column base plates may be subjected to axial loads (compression or tension), with or without major-axis column bending, plus major-axis shear. Base plate bearing pressure is checked as well as bolt tension, if applicable. If shear is present, bolt shear as well as interaction of bolt tension and shear, if applicable, are calculated.
Finally, the required base plate thickness is calculated. There is a separate worksheet for base plate shear lug design, when shear load is high and cannot be effectively handled by bolts.Program Assumptions and Limitations:1.
This program follows the procedures and guidelines of the AISC 9th Edition Allowable Stress (ASD) Manual (2nd Revision, 1995) for wide flange column base plates subjected to axial compressive load only.2. This program uses a 'cubic equation' method of solution for column base plates subjected to axial compression or tension load with major axis column bending as presented in the reference: 'Design of Welded Structures' - by Omer W.
Blodgett (James F. Lincoln Arc Welding Foundation)3. For interaction of anchor bolt tension and shear, this program follows the article: 'Design Aid: Anchor Bolt Interaction of Shear and Tension Loads', by Mario N. Scacco AISC Engineering Journal, 4th Quarter - 1992.4. User has option to take out some of the total shear though friction between column base and grout based on column dead load and coefficient of friction, thus reducing amount of shear to be taken by anchor bolts.5. This program uses the database of member dimensions and section properties from the 'AISC Shapes Database', Version 3.0 (2001) as well as the AISC 9th Edition (ASD) Manual (1989).6.
This program assumes that the base plate is sufficiently rigid to assume linear distribution of load to the base plate and/or anchor bolts. (Note: adequate base plate rigidity is most likely assured if the distance from the face of the column to the edge of the base plate is.
