“PRYING9” Program
| “PRYING9” — AISC 9th ED. PRYING ACTION ANALYSIS PROGRAM |
| Program Description: |
| “PRYING9” is a spreadsheet program written in MS-Excel for the purpose of analysis for prying action in |
| structural steel connections per the AISC 9th Edition (ASD) Code, pages 4-89 to 4-95. Specifically, bolt tension and |
| bolt shear are checked, and the prying force and required thickness are determined. |
| This program is a workbook consisting of three (3) worksheets, described as follows: |
| Worksheet Name |
| Doc |
| Prying Action |
| Allowable Tension Force |
| Program Assumptions and Limitations: |
| 1. The Prying Action worksheet is valid for connections subjected to tension only, or to a combination of tension |
| and shear. |
| 2. The Prying Action worksheet is only applicable for connection bolt diameters from 1/2” to 1-1/2 “ |
| 3. The Prying Action worksheet is only applicable for ASTM A325 or A490 high-strength connection bolts. |
| 4. The Prying Action worksheet is applicable to connection bolts in bearing with threads included in shear plane |
| (N) or threads excluded from shear plane (X), as well as bolts in a slip critical connection (SC). |
| 5. The Prying Action worksheet is applicable to connections with either standard or oversized bolt holes. |
| 6. The Prying Action worksheet also takes fatigue effects into account when required to reduce the allowable bolt |
| tension stress. |
| 7. The Allowable Tension Force worksheet has any applicable assumptions and limitations listed directly below |
| the tables of values. |
| 8. 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”.) |
