Experiments will be performed at various wind speeds and wind directions. A Cobra probe is used to measure the mean and turbulent characteristics of the wind and a 6-DOF load cell is installed under the crane to measure the wind loads experienced by the crane. Later in the week, the proximity model will be changed to a suburban setup to investigate the terrain effects on wind loads imposed on the crane.<u></u><u></u></font></span></p><font

knowledge of potential at-risk construction resources obtained through experimental testing of extreme wind events, this project will partially or fully automatically model the current state of construction sites through machine vision techniques using multimodal visual data obtained from construction workers and camera-equipped unmanned aerial vehicles. To perform multi-physics simulation of multiple discrete objects in unstructured construction sites, an impulse-based discrete element method will be conceptualized. Component-based vulnerability and impact analysis with 3D Building or Civil Information Models (BIM/CIMs) will then be conducted to generate fundamental and highly specific knowledge on wind-induced damage mechanisms. Finally, the entire system will be validated in real-world construction projects and within a 12-fan NHERI Wall of Wind facility that can generate up to hurricane category 5 wind speeds.</span></font></p>
