Grating Strength 2 Years, 10 Months ago Karma: 53  
This thread will track of the version history of the following download:
Grating Strength

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.

Grating Strength updated to v.1.1 2 Years, 10 Months ago Karma: 53  
It was brought to my attention in the "Heavy Duty Steel" worksheet of the "GRATING.xls" workbook that the user could not select potentially any one of all of the available heavy duty grating sizes that were listed in the table.

I had inadvertently stopped the input data validation pick box list at Cell L20, when it should have continued all the way down to Cell L50, to include all of the sizes. The rest of the selection pick boxes in the other worksheets were all right.

I have made this correction, and the new version of this workbook is now 1.1.

Grating Strength updated to v.1.2 2 Years, 8 Months ago Karma: 53  
It was brought to my attention that there was the same text display typo error in each of the calculation worksheets of the "GRATING.xls" workbook.

In the results section and under "Properties", I had inadvertently displayed "Fb = ...." for the modulus of elasticity (E), when it obviously should have been displaying "E = ......". The input data text description was correct, so it was just the text to the right of the input cell that was in error. Kind of surprising that I missed that, and on every sheet no less, but not too surprising that I was consistent through all of the calculation worksheets. There's something to be said for consistency, right? (lol)

I have made the corrections and this workbook is now version 1.2.
