Development of Wind Uplift Standard For Roof Edge Systems and Technologies

屋顶边缘系统包括构件及其与屋顶部件的界面。技术包括设计工具和测试程序。本提案涉及屋顶边缘系统和技术，缩写为：REST。休息是防止风对屋顶影响的第一道防线。在加拿大，组合屋面(BUR)是低坡屋面最常用的组件。从传统的BUR到机械附着式屋面系统(MARS)和粘合剂应用屋面系统(AARS)有了显著的增长和变化。这些创新有助于降低劳动强度，延长屋顶施工流程，并在寒冷的天气条件下解决屋顶组件中的水分迁移问题。然而，目前加拿大屋面界还没有可用的评估标准或设计程序来量化其余部分的动态提升阻力。最近的飓风(Charley、Katrina和Ike)的调查发现REST的主要故障(RICOWI2006、2007、2010以及Baskaraneta 12007和Graham，2004)。本提案是现有CRDPJ305819的扩展，以满足其余地区的研究需求。本提案的目的是开发测试方法、数值模型和设计工具，以造福于屋顶社区。这是一个私人、联邦和大学的合作项目。在这种情况下，研究生将获得大学的理论知识；在独特的NRC实验室设施中进行实验，并通过与行业合作伙伴的互动获得实践经验。

Roof edge systems include components and its interface with the roof assembly. Technologies cover designt ools and test procedures.This proposal addresses Roof Edge Systems and Technologies and abbreviated as:REST. REST is the first line of defence for wind effects on roofs. In Canada, Built-Up Roofs (BUR) is the most commonly used assemblies in low-slope roofs. There is significant growth and changes from the conventional BUR to Mechanically Attached Roofing Sytems (MARS) and Adhesive Applied Roofing Systems(AARS).These innovations contributed to the reduction of labour intensity, extended roof construction processin cold weather conditions and controlled moisture migration issues in the roof assembly. However, at present, no evaluation standards or desing procedures are available for the Canadian Roofing community to quantify the dynamic windup lift resistance of the REST. Investigation from the recent hurricanes (Charley, Katrina and IKE) identified major REST's failures (RICOWI2006,2007,2010 and Baskaraneta12007andGraham,2004).The present proposal is an extension of the existing CRDPJ305819 to address the research needs of the REST. The aim of the present proposal is to develop test methods,numerical models and design tools for the benefit of the roofing community. This is a private, federal and university partnership project. In such,the graduate students will acquire the oretical knowledge at the university; perform experiments at the unique NRC lab facilities and gain practical experiences by interacting with industrial partners.
