The 2020 National Snow Load Study

Brennan Bean, Marc Maguire, Yan Sun, Jadon Wagstaff, Salam Adil Al-Rubaye, Jesse Wheeler, Scout Jarman & Miranda Rogers
The United States has a rich history of snow load studies at the state and national level. The current ASCE 7 snow loads are based on studies performed at the Cold Regions Research and Engineering Laboratory (CRREL) ca. 1980 and updated ca. 1993. The map includes large regions where a site-specific case study is required to establish the load. Many state reports attempt to address the "case-study regions" designated in the current ASCE 7 design...

Supplementary files for \"Creating a Universal Depth-To-Load Conversion Technique for the Conterminous United States using Random Forests\"

Jesse Wheeler, Brennan Bean & Marc Maguire
As part of an ongoing effort to update the ground snow load maps in the United States, this paper presents an investigation into snow densities for the purpose of predicting ground snow loads for structural engineering design with ASCE 7. Despite their importance, direct measurements of snow load are sparse when compared to measurements of snow depth. As a result, it is often necessary to estimate snow load using snow depth and other readily accessible...

Ground Snow Loads for ASCE 7-22 – What Has Changed and Why?

Marc Maguire, Brennan Bean, James Harris, Abbie Liel & Scott Russell
The changes to the ASCE 7 ground snow load maps proposed for the 2022 edition target a uniform reliability rather than a uniform hazard – an important distinction – and are the first of their kind in ASCE 7. Previously, the ASCE 7 snow loads used a uniform-hazard 50-year mean recurrence interval (MRI) with a 1.6 load factor. The newly proposed loads directly target the safety levels stipulated in Chapter 1 of ASCE 7, resulting...
