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.

该学院早期职业发展（CAREER）计划奖的目的是确定屋顶形状和覆盖物对扬压力的影响，以及受到飓风影响的柔性屋顶系统的动态响应。这一目标将通过在佛罗里达国际大学的12扇风墙（WoW）模拟实验室进行全面测试来实现。教育目标是增加飓风工程学术课程的本科生人数。该项目的目标是：（1）通过模拟关键部件附近的局部流场，确定全尺寸试验可以在多大程度上改善屋顶峰值压力估计;（2）通过全尺寸试验确定柔性屋顶系统在强风下的动态响应;（3）协同整合低矮建筑空气动力学研究与归纳学习，以促进提高本科生在飓风工程方面的知识。预期的贡献包括：（1）新的载荷修正函数，以改善现有的空气动力学数据库中的峰值估计;（2）在损伤开始之前和损伤传播过程中，对屋面板中渐进载荷分布的新知识;（3）教育和影响本科生和研究生职业道路的新战略框架。该研究有望造福社会，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弹性。建筑法规和标准的这些变化将改善低矮建筑的施工做法，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。将通过从少数民族服务机构积极征聘人员，促进代表性不足的群体扩大参与这一迷人的主题领域。该项目的教育贡献将是显着的，越来越多的学生追求的职业道路的飓风合格的工程师。将通过展示12个风扇的魔兽世界设施和可移植到地球仪的风/飓风工程课程的归纳学习模块的宝贵使用，加强研究和教育基础设施。将通过在各种论坛和出版物上的介绍，广泛开展外联活动。
