Wind load on a container crane located in atmospheric boundary layers

Wind environment nearby a container crane located in a port was simulated in a wind tunnel test section. A 1 150 scale-downed model of the container crane was embedded in an atmospheric boundary layer (ABL). Wind load acting on the container crane model was measured using a seven-component balance with varying wind direction (yaw angle) in two different ABLs. Reynolds number effect on the aerodynamic coefficients was investigated with varying Reynolds number. Effects of ABL, adjacent structures and boom positions on the wind load variation were evaluated experimentally. In addition, the effect of the minute structures attached at the crane model such as stairways, wheels, handrails, etc., were also investigated in this study.
