Measurement of Aerodynamic Performance of the Houston Ship Channel Bridge

本项目是对南岸镇（北卡罗莱纳州）低层训练设施结构的风荷载和结构阻力数据进行分析。在“蓝天计划”的支持下，PI正在皮茨培训中心安装一个全面的测量系统。该计划由南岸镇开发，由联邦应急管理局和工业赞助商资助。该系统将记录多年的风环境、压力和结构响应。对收集到的数据进行分析将采用最先进的程序，并根据风力工程的情况对这些程序进行裁剪和进一步发展。具体来说，除了常规的统计分析，小波变换将被用作一个基本的工具，以提高对崖体空气动力学中涉及的物理过程的理解。此外，预计这些技术将通过使用风洞技术提高我们在钝面结构上模拟风荷载的能力。如果该结构在未来两年内经历大西洋风暴，在强风（直至飓风）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，并有可能提供对低层结构的风荷载的见解，这在以前是不可能的。＊＊＊

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. ***
