9713739 Jones This project is to conduct the analysis of wind load and structural resistance data from the Town of Southern Shores (North Carolina) low-rise training facility structure. With the support of Project Blue Sky - developed by the Town of Southern Shores and funded through FEMA and industrial sponsor - the PI is installing a full-scale measurement system in the Pitts Training center. The system will record the wind environment, pressures, and structural response for a multi-year period. The analysis of the collected data will be made using state-of- the-art procedures, and the tailoring and further development of those procedures to the wind engineering context. Specifically, in addition to routine statistical analyses, the wavelet transform will be used as a fundamental tool to improve understanding of the physical processes involved in bluff-body aerodynamics. In addition, it is envisioned that these techniques will improve our ability to model wind loads on bluff structures through the use of wind tunnel techniques. If the structure experiences Atlantic storms over the next two- year period, the likelihood that high-quality data will be collected under strong- (up to hurricane-) wind conditions is high. These data will be unique, and potentially will provide insights into wind loading on low-rise structures that have heretofore been impossible. ***

9713739 Jones本项目旨在对南海岸镇（北卡罗来纳州）低层训练设施结构的风荷载和结构阻力数据进行分析。 在蓝天项目的支持下-由南海岸镇开发，并通过联邦应急管理局和工业赞助商资助-PI正在皮茨培训中心安装一个全面的测量系统。 该系统将记录多年的风环境、压力和结构响应。 将使用最先进的程序对收集的数据进行分析，并根据风力工程背景对这些程序进行剪裁和进一步开发。 具体地说，除了常规的统计分析，小波变换将被用来作为一个基本的工具，以提高理解的物理过程中涉及的钝体空气动力学。 此外，可以预见的是，这些技术将提高我们的能力，通过使用风洞技术，对海崖结构的风荷载建模。 如果该结构在未来两年经历大西洋风暴，则在强风（高达飓风）条件下收集高质量数据的可能性很高。 这些数据将是独一无二的，并可能提供深入了解风荷载对低层结构，迄今为止是不可能的。 ***
