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.

这个教师早期职业发展（职业）计划奖的目的是确定屋顶形状和覆盖物对抬高压力的影响以及受飓风风的柔性屋面系统的动态响应。该目标将通过在佛罗里达国际大学的12扇风墙（WOW）模拟实验室中的全面测试来实现。教育目标是增加飓风工程学术课程中的本科生的数量。该项目的目的是：（1）确定全面测试可以通过模拟关键组件附近的本地流场来改善屋顶峰值估计的程度； （2）通过全面测试确定受大风的柔性屋顶系统的动态响应； （3）协同整合低建筑物的空气动力学研究，以促进飓风工程学的本科生知识的改善。预期的贡献包括：（1）新的负载修改功能，以改善现有空气动力学数据库中的峰值估计； （2）在损坏启动之前屋顶子组件之间进行渐进式负载分布的新知识，并随着损害传播； （3）教育和影响本科和研究生的职业道路的新战略框架。预计该研究将使社会受益，因为它具有显着改善建筑法规和标准的潜力，以提高容易受到飓风风损害的低建筑物的弹性。建筑法规和标准的这些变化将改善低建筑物的建设实践，并减少飓风风暴中的损害。通过归纳学习将新知识逐步融合到新知识中，发现的进步将纳入教育中。将通过从少数族裔服务机构的积极招募这个引人入胜的主题领域来促进代表性不足的群体的扩大参与。通过增加追求飓风合格工程师职业道路的学生数量，该项目的教育贡献将是重要的。通过证明可将12粉丝WOW设施的宝贵使用以及可运输到全球风/飓风工程课程运输的能力学习模块的宝贵使用，将增强研究和教育基础设施。外展活动将通过在各种论坛和出版物上的演讲中广泛进行。
