Description

"GRATING.xls" is a workbook containing 9 worksheets for the purpose of analysis and design of welded steel grating and fabricated aluminum bar grating.  

Specifically, light duty steel or aluminum grating covered floors, platforms, walkways, trenches, etc. subjected to uniformly distributed gravity loading (dead + live), along with a concentrated line load may be analyzed.  Light duty steel or aluminum grating may also be analyzed for an imposed wheel or post load.  Heavy duty steel grating may be analyzed for vehicular wheels loads from either lift trucks with designated capacity or from AASHTO truck loading (H-20 and H-15).  Bending stresses and deflections are checked against allowable values.  

Allowable load tables for grating are also included for quick selection of grating size or clear span based on either uniformly distributed or concentrated line loading, and allow for user input of a clear span value not specifically noted in the tables.
