If you're shoveling a tad too much, you can damage the roofing tiles. Engineering. Hi there, Please could anyone point me in the right direction. It also informs you whether you should immediately remove some of the snow, or you can wait a little bit longer. G-8) Wind. As you can see in the table below, its density is over 15 times higher than the density of fresh snow! Snow Drift Load (obstruction) — (Fig. Snow Load Calculations. Calculators. sAd (EN 1991-1-3 § 5.2 (3) b)) include drift effects but no local effects. Balanced Snow load: = 26.9 psf 96.5 psf Sliding Snow - onto lower roof Sliding snow = 0.4 Pf W = 0.0 plf Distributed over 15 feet = 0.0 psf hd + hb = 1.40 ft hd + hb < =h therefore sliding snow =0. As you might expect, buildings of high importance, such as power plants, schools or hospitals need to be more snow-resistant, and so can withstand a higher load. Just buy a Geo-Zone Tool data package in our webshop and continue to use the service as a registered user. Procedures and guidelines set out by ASCE in ASCE 7-10 give the structural engineer direction on what these loads are depending on your location in the United States, and how to apply them. If your roof is pitched, enter the length and width of the flat area covered by the roof. Our calculator allows you to choose the state you live in, and - in the case of Alaskan locations - the specific city. Example: On the Snow Load dialog screen, how exactly is the snow load calculated for weight / Length = 0.5 lbs/in for both a 2 inch dia pipe and 12 inch dia pipe that are both 1 ft long piece of pipe. Remember, though, that each province has adopted the NBC document with minor tweaks and adjustments to account for the specifics of the region, so the real value might differ slightly from the one provided by our snow load calculator. This loading is likely to be far greater than the equivalent static load. In these situations, make sure to act quickly - any delay may be potentially dangerous for both the structure and the residents! Snow loads on the roof. gantry girders, bearings 3 15 – 30 … Use of the output of this website does not imply approval by the governing building code bodies responsible for building code approval and interpretation for the building site described by latitude/longitude location in the report. You can also find the load per square meter or square foot of roofing by opening the advanced mode. Please remember that the numbers given by this calculator are just an approximation and are by no means 100% accurate. If the roof seems damaged, don't attempt to clean it, as it might collapse - instead, contact a structural engineer to assess the scope of the problem. The effect of snow loads on a structure can have dire implications if not taken into account during the design period. Solar panels. Secondly, as mentioned before, leave a thin layer of snow - if you don't, you might damage the tiles and cause leaks through the roofing. An architect or engineer should be able to work out the design wind load that we will need in our calculations. When in doubt, it's better to shovel in advance! Geo-Zone Tool: Snow, Wind, and Seismic Zone Maps, NA+A2:18 to BS EN 1991-1-3:2003+A1:2015  |  http://www.gadm.org/download  |  http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp. If you live in the US, our snow load calculator compares the total weight on your roof with the permissible load calculated according to the standards issued by the American Society of Civil Engineers regarding the Minimum Design Loads for Buildings and Other Structures (ASCE7-16). Building roof length lu = 170.0 ft Projection height h = 10.0 ft Snow density γ = 19.2 pcf Balanced snow height hb = 1.40 ft hc = 8.60 ft hc/hb >0.2 = 6.1 Therefore, design for drift Drift height hd = 3.63 ft Drift width w = 14.50 ft Surcharge load: pd = g*hd =69.6 psf Less snow will accumulate on a slippery roof - it will slide off instead. This was only an example, as drifted snow is Online Snow Load Calculator(for Buildings with Flat or Low Slope Roofs - for Balanced Snow, Drift, and Rain-on-Snow Surcharge Loadings) calculator (ASCE 7-05) for structural engineers, construction professionals and building planners.
