The proposed research is aimed at developing a differential force sensor that can measure only wind-induced force in aeroelastic wind tunnel tests without the influence of the inertial force of the specimen. In the current practice, aeroelastic wind tunnel tests are used to evaluate the interaction between structures, such as high-rise buildings or long-span bridges, and wind loads. From the conventional tests, only wind-induced deformation is measured. Understanding the applied wind force in the tests can improve the understanding of how the movement of structures influences wind loads and vice versa. In addition, the measured wind force can be directly used for new wind tunnel test methods referred to as real-time aeroelastic hybrid simulations. The research project will provide training opportunities to two HQPs: a post-doctoral researcher and an undergraduate student. The HQPs will broaden their understanding of structural engineering, finite element analyses, instrumentation, and measurements. They will closely interact with the collaborators at Seoul National University, which will help them learn how to work in a global working environment. Furthermore, through the research group's monthly activities related to equity, diversity, and inclusion (EDI), the HQPs will enhance their understanding of the importance of EDI.

本研究旨在开发一种差动力传感器，在气动弹性风洞试验中仅测量风致力，而不受试件惯性力的影响。在目前的实践中，气动弹性风洞试验用于评估高层建筑或大跨度桥梁等结构与风荷载之间的相互作用。传统测试仅测量风引起的变形。了解测试中施加的风力可以提高对结构运动如何影响风荷载的理解，反之亦然。此外，测量的风力可以直接用于称为实时气动弹性混合模拟的新风洞测试方法。该研究项目将为两名HQP提供培训机会：一名博士后研究员和一名本科生。总部将拓宽他们对结构工程、有限元分析、仪器仪表和测量的理解。他们将与首尔国立大学的合作者密切互动，这将帮助他们学习如何在全球工作环境中工作。此外，通过研究小组每月与公平、多样性和包容性 (EDI) 相关的活动，总部将增强对 EDI 重要性的理解。
