| Abstract | In order to verify the seismic capacity of reinforced concrete containment vessel (RCCV) under the design earthquake level of SL-2 (peak acceleration 0.25g), shaking table tests of a 1:15 model RCCV are carried out. The El Centro earthquake motion record, the Taft earthquake motion record as well as an artificial earthquake acceleration are employed as the input excitations. There are three load cases for each test stage, with the peak ground acceleration (PGA) being 0.1g, 0.2g and 0.3g, respectively, corresponding to 0.088g, 0.175g and 0.263g for the prototype RCCV structure because of the acceleration ratio of 1.14. The test results indicate that under the earthquake excitation of the acceleration peak 0.1g, 0.2g and 0.3g, the tensile strains at monitoring points on the cylinder don’t reach the cracking level. Using the general-purpose nonlinear finite element analysis program ANSYS, a three-dimensional (3D) model of the scaled model reinforced concrete containment vessel is modeled. The numerical simulation analysis results could match the results of the tests very well. It is shown by the results of the shaking table tests that the model RCCV is still within the elastic range as a whole. In order to analyze the yield displacement of the RCCV, a static nonlinear pushover analysis of the RCCV is carried out. The result shows that the RCCV had sufficient seismic safety margin. |

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.
