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.
