본 연구에서는 특정한 콘테이너 크레인을 설계도면에 따라 100:1 축척의 모형 을 제작하고 Reynolds 수에 의한 축척영향, 모형취부 및 계측 시스템의 반복성 영향, 풍향에 따른 특성, boom의 위치에 따른 특성, 풍고도에 따른 특성, blockage 영향, 설 계변경에 따른 효과에 주 관심을 두고 연구하였다. 특히 설계단계에서 관련 규격에 따라 예측된 풍하중이 실제와 어느 정도로 일치하는지에 관심을 두고 풍동시험 결과와 비교했다.
A container crane model was tested to investigate wind-load characteristics in uniform flows and ground boundary layers. Drag coefficients and moment coefficients show their minimum values at 0, 90, 180 degrees wind directions and maximum values at 60 and 120 degrees. Strong interactions among structure elements produce such variations of the wind-load with wind directions. The BS-2573 code is shown to over-estimation can be reflected in the design stage of cranes by refining the rule of the designer. Some roundings of coners of the engine room and the machinery room reduce the wind-load by 10 percents. Considerable reductions of the wind-load would be expected if further integrated development of the crane structure are executed.
