Abstract: An investigation of unbalanced or drifted snow loading on single gable roofs is presented. A database of 28 case histories was developed and analyzed to identify trends and key parameters for this type of roof snow drift. ...

Abstract: The evaluation of structural loads due to drifted snow on a multilevel roof is considered. A detailed case history is presented that highlights the two types of drifts that form on multilevel roofs. The two types of snowdrift ...

Abstract: A study of structural loading on gable roofs due to rain falling on an existing roof snowpack is presented. Rain-on-snow provisions in various existing standards are reviewed, and a summary of structural damage in the ...

Abstract: Drift loads on roofs are arguably the most important snow load from a structural engineering perspective in the US, as they are the governing load for most cases of snow related structural collapse. Design relations for ...

Abstract: A method is presented for determining snow drifts at roof steps in series. The method is based upon provisions in the current

Abstract: Drift loads on roofs are arguably the most important snow load from a structural engineering perspective in the US, as they are the governing load for most cases of snow related structural collapse. Design relations for ...

Abstract: Current code provisions for drift snow loads on multilevel roofs are examined in light of recent research results from a statistical study of approximately 350 drift load case histories. New provisions are proposed in which ...

Abstract: The static horizontal stiffness of pile foundations, for which there is continuous contact between the bottom of the pile cap and the underlying soil, is studied. Finite element results for a single pile with a circular ...
