[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]"ASCE702S" is a spreadsheet program written in MS-Excel for the purpose of flat roof snow loading analysis for[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]buildings and structures per the ASCE 7-02 Code. Specifically, coefficients and related and required parameters[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]are selected or calculated in order to compute the net design snow loads, including snow drift due on lower roofs[/FONT][/FONT][/COLOR][/COLOR]

[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]1. This program specifically follows Section 7.0, Snow Loads, of the ASCE 7-02 Standard, "Minimum Design[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]Loads for Buildings and Other Structures".[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]2. This program assumes only snow loading analysis for buildings with a flat roof, or low slope roof <= 5 degrees.[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana](Note: for reference, a 1:12 roof slope equates to 4.76 degrees, and the program allows a slope up to 1.05:12.)[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]3. This program addresses only balanced snow loading, snow drifts on lower roofs, and rain-on-snow surcharge[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]loading. Unbalanced roof snow loads are not considered.[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]4. This program assumes the possibility of either leeward or windward snow drifts, and the larger of the two[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]calculated drift heights per the code is used as the design drift height. Leeward drift results from snow blown[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]off a high roof onto a lower roof. Windward drift results from snow blown against a projection or wall below a[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]high roof.[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]5. This program determines any rain-on-snow surcharge loading when applicable. Rain-on-snow surcharge[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]loading is not required for ground snow loads, pg > 20 psf, nor for roof slopes >= 0.5:12 (2.38 degrees).[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]This program conservatively combines the rain-on-snow surcharge loading with snow drift loading. However,[/FONT][/FONT][/COLOR][/COLOR]
[COLOR=#333333][COLOR=#333333][FONT=Verdana][FONT=Verdana]per Code, rain-on-snow surcharge loading need not be combined (superimposed) with snow drift loading.[/FONT][/FONT][/COLOR][/COLOR]
