Because of New Hampshire's hilly landscape, mapped values of ground snow load are not available for much of its area. We conducted snow load case studies to establish ground snow loads for a specific elevation in each of the 140 towns where no values are currently available. That work was done by three researchers and three structural engineers practicing in New Hampshire. While our methods of analysis varied somewhat, our results were comparable and the feedback we received from each other was quite valuable. We then established an elevation correction factor to transfer our snow load answers to other elevations in each town. We did not do case studies for the 102 towns in New Hampshire where mapped values are available. We are now planning to do that, as we believe that case studies improve snow load design criteria. We suggest that similar studies be conducted for other places in the United States.

This volume presents the background to the recently developed European standard (CEN standard) on snow loads. Many of the papers on ""structural engineering"" describe results from a European snow project that was completed in 1999.

Specialists in building and civil engineering, architecture, traffic and transport engineering, urban planning and avalanche science came together at the Fifth International Conference on Snow Engineering, organized by the Federal Swiss Institute for Snow and Avalanche Research in Davos 2004. This event belongs to a series of Snow Engineering Confe
