Analyses. This note describes the process to update a Canadian historical snow survey dataset to 2016 and the production of a 0.1° gridded version for research applications. The structural design and field review of non-structural elements, restraints, and anchorages shall be provided by a professional engineer registered in B.C. This paper describes the development of a new snow load map for defining ground snow loads for building (roof) design in the state of Colorado. The Ontario Building Code | Specified Snow Load 4.1.6.2. Structural Design of Non-Structural Components. I-7) Wind load — Walls (Fig. 7. I-24) Earthquake Load Calculators. An estimated snow depth map Specified Snow Load (1) The specified load, S, due to snow and associated rain accumulation on a roof or any other building surface subject to snow accumulation shall be calculated from the formula, S = I s [S s (C b C w C s C a) + S r]. Understanding current conditions is the starting point, and the most critical part, of any weather forecast. I-8) Wind load — Free standing plates, walls, and billboards (Fig. Wind Load Calculators — Low rise buildings. The ground snow load map shown below was scanned from the ASCE 7-10 (Figure 7-1). National, US Snow Depth Map, covering much of Canada. A second alternative to using the Zone map found below would be to use the chart found on the Zone map to determine the ground snow load for the specified geodetic elevation. Snow drift load and distributions for areas adjacent to roof obstructions. Primary Structural Action (Fig. Hundreds of weather stations, ships, and aircraft across Canada, the US, and the rest of the world report readings of temperature, pressure, wind, moisture and precipitation. Design shall accommodate all applicable load conditions (dead loads, live loads, wind loads, and seismic loads) and must conform to the current edition of the BC Building Code. In areas of the state outside of certified local government jurisdictions, the design snow load shall be based on the ground snow loads developed in "Snow Loads for Structural Design in Montana", authored by F.F. For an elevation of 212 metres, the ground snow load would be: 1.2 + (1.4/215) * (212-75) = 2.1 kilopascals . Ground snow loads, p g , for the contiguous United States can generally be determined using this map. The Canadian Ice Thickness Program has two data collections that users can access anytime online: Ice Thickness Program Collection, 1947 to 2002 [XLS;4.1 MB] | Metadata; Ice Thickness Program Collection, Fall 2002 to 2020 [XLS; 182 KB]; The ‘Original Ice Thickness Program Collection’ contains ice thickness and snow depth measurements for 195 sites. Videon and J.P. Schilke, Civil & Agricultural Engineering, Montana State University, August 1989. where, I s = importance factor for snow load as provided in Table 4.1.6.2., 1. In the 1985 edition of the National Building Code of Canada (NBCC) the intensity of the specified snow load at any location on a roof is obtained by multiplying the ground snow load for … AccuWeather's Forecast map provides a 5-Day Precipitation Outlook, providing you with a clearer picutre of the movement of storms around the country.
