| Abstract | In connection with wind sensitivity for the large towering and open truss-type offshore jacket platforms subject to hurricanes, the wind-survivability of this large structure has attracted more attention. An innovative wind-survivability framework for the large offshore jacket platform is presented based on the performance-based analysis in this paper. The damage states of a large offshore jacket platform located in the South China Sea are divided into five grades DS1 ∼ DS5 under hurricanes, including intact, minor damage, moderate damage, severely damaged and collapsed, also the corresponding ultimate damage states LS1 ∼ LS4 are defined and derived. The results show that the braces yield failure on the bottom and top horns of the derrick are the main failure modes of the large jacket platform, which should be stronger reinforced to ensure their safety performances; the different ultimate damage state determination factors have a little influence on the wind-survivability envelopes of the jacket platform; the hurricane return period for the minor damage of the towering derrick is about 15 years, also the moderate damage is about 25 years, the severely damaged is about 165 years and the collapsed is about 225 years. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
