Wind Load Calculator 1

[medeek]

I've recently started working on a wind load calculator. Does anyone know of any free wind load calculators that I can use to check my own program against. I am going to program it for MWFRS using the direction procedure. I will make it a web based program like my other programs and try to employ some SVG that can present the data with some visual aid something like the image below:

Are you sure "any free wind load calculators" will give you results more valid than your own?

No, but if you check your work against someone else's you are almost always going to be assured that you are both correct. If they don't match then one or the other is probably wrong. Its a good way to error check one's code.

LOL
yeah, that always works.

I've just finished adding the PDF report output to the new Wind Load Calculator (Envelope Procedure ASCE 7-10). Currently it calculates the MWFRS loads, I am thinking about adding in the C&C loads as well just to complete the package. I am still undecided on how best to incorporate the half hip and dutch gable type roofs.

Yesterday while I was putting Woodworks software through its paces, I compared their shearwall values to the ones calculated by the wind load calculator (envelope procedure). The lateral loads compared exactly with no overhangs present. However, when I updated the model in Woodworks and in my calculator to include overhangs there was a slight difference. I spent almost 4 hours trying to determine the discrepancy. My conclusion is that the only difference is the windward overhang pressure is being calculated slightly different than the method I am using. The difference is not huge (10%) but noticeable. I have not been able to determine the method Woodworks software is using to calculate the lateral load imposed by the windward overhang pressure (underside of overhang, positive pressure). I attempted to contact their help desk however their web based form in not functioning and I can't seem to find an email anywhere on their site.
