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

该学院早期职业发展(Career)计划奖的目标是确定屋顶形状和覆盖物对扬起压力的影响，以及柔性屋顶系统在飓风下的动态响应。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项目的本科生数量。该项目的目标是：(1)通过模拟关键部件附近的局部流场，确定全尺寸测试可以改善屋顶峰值压力估计的程度；(2)通过全尺寸测试确定柔性屋顶系统在大风下的动态响应；以及(3)将低建筑空气动力学研究与归纳学习相结合，以促进本科生在飓风工程方面知识的提高。预计的贡献包括：(1)新的载荷修改功能，以改进现有空气动力学数据库中的峰值估计；(2)关于在损伤开始之前和在损伤传播时屋顶组件之间的渐进载荷分配的新知识；以及(3)用于教育和影响本科生和研究生的职业道路的新战略框架。预计这项研究将使社会受益，因为它有可能显着改进建筑规范和标准，以增强易受飓风破坏的低矮建筑的弹性。建筑规范和标准的这些变化将改善低矮建筑的施工实践，并减少飓风风暴中的破坏。通过逐步将新知识与归纳学习相结合，将发现的进步融入到教育中。将通过积极从少数群体服务机构招聘这一引人入胜的主题领域来促进代表不足群体的更广泛的参与。这个项目的教育贡献将是巨大的，因为越来越多的学生追求飓风合格的工程师的职业道路。研究和教育基础设施将通过示范使用有价值的12扇WOW设施和可移植到全球各地的风/飓风工程课程的归纳学习模块来得到加强。将通过在各种论坛和出版物上的发言广泛开展外联活动。

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.
