Snow Drift Loads

该项目将在以前工作成果的基础上，研究多层屋顶上的雪堆负荷，目的是扩大现有的知识库。这将通过考虑环境因素，即风和可漂浮的雪来实现，以量化这一危险。现有的和测量的风雪信息将用于这一量化。这项工作的第二项任务涉及对漂移形成机制的现场调查。该项目的成果将用于屋顶的结构设计，使其在这些极端的雪荷载下不会坍塌。

The project will study snow drift loads on multilevel roofs, building on the results of previous work, and with the objective of broadening the existing knowledge base. This will be accomplished by taking into account environmental factors, namely wind and driftable snow, for the quantification of this hazard. Existing and measured wind and snow information will be used for this quantification. A second task of this work involves a field investigation of the mechanics of drift formation. The results of the project will be used in the structural design of roofs that will not collapse under these extreme snow loads.
