Model Test of Wind Load Characteristic of 7 500 t Floating Crane
摘要
Abstract
Wind tunnel test of a 7 500t floating crane was conducted with a 1∶200 scaling model.The balance force was measured to discuss structure response against different working conditions and wind in-let angle.78 working conditions were considered according to 3 typical luffing angles,2 possible wind field landscapes and 1 3 wind inlet angles.The test results were concluded to non-dimensional results.The re-sults indicate that:1)wind load along isometric direction (135°wind angle)reaches the highest point;2) The smaller the luffing angle,the larger the wind load;3)The wind field landscape plays a small role in wind response.关键词
