As the first part of the study, an axisymmetric loading condition for an upright tank position is considered. The buckling collapse test of scaled models is performed under the loading condition similar to the partially filled condition. The non-linear FE analyses of the test models are carried out and the results are compared with the test results to verify the accuracy of the imperfection sensitivity obtained by the FE analysis. A method to estimate the reduction factor of the elastic buckling strength due to initial shape imperfection is proposed by introducing a concept of an equivalent toroidal shell analogy and applying the Hutchinson’s solution to the toroidal shell under combined circumferential compression and meridional tension based on the Koiter’s initial post-buckling theory. A simplified method to estimate the elastoplastic buckling strength is also proposed by applying the Mises’s type plastic correction to the estimated elastic buckling strength. The reasonable accuracy of the estimated elastic and elastoplastic buckling strengths is demonstrated through a comparison with the results of scaled model tests and FE analyses.","PeriodicalId":192323,"journal":{"name":"Journal of the Japan Society of Naval Architects and Ocean Engineers","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123541236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the ship size grows, the number of bays in which containers are loaded will increase, and the number of containers per bay will also increase. The loading order of a large number of containers is usually optimized by a computer-aided planning system called a Loading Computer that can comprehensively consider ship stability and cargo handling efficiency. However, due to the increase in the size of ships, the number of ports of call in one voyage and the number of empty containers to be transported also increase, and the container loading patterns are more diverse than before. There is more than one solution. On the other hand, the loading condition of the containers on deck affects the wind forces during the voyage. The above-mentioned Loading Computer does not consider the wind forces acting on a ship, but from the viewpoint of improving energy efficiency, it is desired to consider the wind forces that change depending on the loading patterns as one parameter. In this paper, the relationship between the loading patterns of containers on deck and wind forces was clarified by means of wind tunnel tests, focusing on the number of gaps between container bays.","PeriodicalId":192323,"journal":{"name":"Journal of the Japan Society of Naval Architects and Ocean Engineers","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121646167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
