Abstract: The U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) has mapped ground snow loads for much of the United States. In some areas where extreme local variations preclude mapping on a national scale, instead of loads, “CS” is used to indicate that Case Studies are needed. This report and the accompanying spreadsheet, which contains the 15,104-station CRREL ground snow load database, provide the information needed to conduct Case Studies. When the latitude, longitude, and elevation of a site of interest are provided, the spreadsheet tabulates data available in the vicinity and generates plots that relate ground snow loads nearby to elevation. With this information, the ground snow load at the site of interest can be determined. This report uses 10 examples to illustrate the methodology and provides our answer and the comments we generate for each of these Case Studies and for 16 additional sites of interest, 8 of which have their answers “disguised” for practice purposes. CRREL has conducted over 1000 Case Studies upon request. Practicing structural engineers were involved in over 250 of them to verify that this methodology is ready to transfer to the design profession.
Description: Technical Report
NOTE: The file "SLCS 1.0.xlsm" below is a spreadsheet intended for use with this technical report
NOTE: The "Master Data.xlsx" spreadsheet contains the 15104-station CRREL ground snow load database. It is a “block formatted” version of the master data in the “SLCS 1.0.xlsm" spreadsheet used to conduct snow load case studies for the United States. The case study spreadsheet was formatted to produce “Case Studies” whereas this condensed version is the same data formatted for easier access.
