CAREER: Full-Scale Simulation of Peak Responses to Reduce Hurricane Damage to Low Buildings and Use of Related Research to Develop Hurricane-Engineering Expertise

这个教师早期职业发展（Career）项目的目标是确定屋顶形状和覆盖物对上升压力的影响，以及飓风对柔性屋顶系统的动态响应。这一目标将通过佛罗里达国际大学12扇风墙（WoW）模拟实验室的全尺寸测试来实现。教育目标是增加飓风工程专业本科学生的数量。该项目的目标是：(1)通过模拟关键部件附近的局部流场，确定全尺寸测试在多大程度上可以改善顶板峰值压力估算；(2)通过全尺寸试验确定柔性屋面系统在大风作用下的动力响应；(3)将低层建筑空气动力学研究与归纳学习相结合，促进本科生飓风工程知识的提高。预期贡献包括：(1)新的载荷修正函数，以改进现有气动数据库中的峰值估计；(2)在损伤发生前和损伤传播过程中，对顶板组件间累进荷载分布有了新的认识；(3)对本科生和研究生的职业道路进行教育和影响的新战略框架。这项研究有望使社会受益，因为它有可能显著改善建筑规范和标准，以提高易受飓风破坏的低矮建筑的恢复能力。这些建筑规范和标准的变化将改善低层建筑的施工实践，减少飓风风暴造成的损失。通过逐步将新知识与归纳学习相结合，将发现的进步纳入教育。将通过积极从少数民族服务机构招聘这一引人入胜的学科领域来促进代表性不足的群体的更多参与。这个项目的教育贡献将是显著的，因为它增加了追求飓风合格工程师职业道路的学生的数量。研究和教育基础设施将通过示范有价值地使用12扇WoW设施和可运输到全球风/飓风工程课程的归纳学习模块来加强。将通过在各种论坛和出版物上发表演讲，广泛开展外联活动。

The objective of this Faculty Early Career Development (CAREER) Program award is to ascertain the effects of roof shapes and coverings on uplift pressures and the dynamic response of flexible roofing systems subjected to hurricane winds. This objective will be accomplished through full-scale testing in the 12-fan Wall of Wind (WoW) simulation laboratory at Florida International University. The educational objective is to increase the number of undergraduate students in hurricane engineering academic programs. The project aims are to: (1) determine the extent to which full-scale testing can improve roof peak pressure estimates by simulating local flow fields near critical components; (2) determine through full-scale testing the dynamic response of flexible roofing systems subjected to high winds; and (3) synergistically integrate low building aerodynamics research with inductive learning to foster improvement in undergraduate student knowledge in hurricane engineering. The expected contributions include: (1) new load modification functions to improve peak estimates in existing aerodynamic database; (2) new knowledge on progressive load distribution among roof subassemblies before damage initiation and as damage propagates; and (3) new strategic framework for educating and influencing the career path of undergraduate and graduate students. The research is expected to benefit the society as it has the potential of significantly improving building codes and standards to enhance the resiliency of low buildings that are vulnerable to damage in hurricane winds. These changes in building codes and standards will improve construction practices of low buildings and reduce damages in hurricane storms. Advancement of discovery will be incorporated in to education through step-by-step integration of new knowledge with inductive learning. Broadening participation of underrepresented groups will be fostered through active recruitment from minority serving institutions for this fascinating subject area. The educational contribution of this project will be significant by increasing number of students pursuing a career path of hurricane-qualified engineers. Research and education infrastructure will be enhanced through demonstration of valuable use of the 12-fan WoW facility and inductive learning modules transportable to wind/hurricane engineering curriculum around the globe. Outreach activities will be broadly pursued through presentations at various forums and publications.
