"CLIPCONN" is a spreadsheet program written in MS-Excel for the purpose of analysis of steel beam end connections using double clip angles either welded or bolted to the beam web, and bolted to either the column flange, column web, or girder web. The connections may be subjected to end shear reaction and/or axial load. Specifically, all applicable "limit states" for the end connection analysis pertaining to the clip angles, bolts, beam web, column flange or web, and girder web are checked.
This program is a workbook consisting of eight (8) worksheets, described as follows:
Program Assumptions and Limitations:
1. This program follows the procedures and guidelines of the AISC 9th Edition Allowable Stress (ASD) Manual (1989) and the AISC 9th Edition Manual Vol. II - Connections (1992).
2. 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).
3. This program assumes that the tension capacity for any "limit state" is reduced by the presence of shear. For allowable bolt tension in the presence of shear, the "interaction" (combined stresses) is handled directly by the AISC Code equations. For other "limit states" in combined stresses such as bolt bearing, gross and net shear and tension, and block shear and tension tearout, the effect of "interaction" is handled by use of the formula, P/Ra+(R/Rv)^2=1, as suggested from the following reference:
"Combined Shear and Tension Stress" - by Subhash C. Goel, AISC Journal, 3rd Qtr.-1986.
Thus, the reduction factor applied to the tension "limit state" capacity is = (1-R/Rv)^2.
where:R = actual shear end reaction
Rv = allowable shear capacity for the particular "limit state" considered
4. This program follows the procedure for "yield line" theory for the flexural analysis of either a column web or a girder web subjected to an axial load, as outlined in "Connections" by Larry S. Muir and William A. Thornton and published by Cives Steel Company.
Note: This booklet is a reprint of Chapter 3, from the "Structural Steel Designer's Handbook, 4 th Edition.
5. This program contains numerous “comment boxes” which contain a wide variety of information including explanations of input or output items, equations used, data tables, etc. (Note: presence of a “comment box” is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move the mouse pointer to the desired cell to view the contents of that particular "comment box".)

Does the CLIPCONN spreadsheet account for axial transfer forces; in other words, would a beam connected to a column web with a relitivly large tension axial force account for hte prying action? Thank you. Really like all of your spreadsheets
