| Abstract | This paper proposes a new criterion called the ratio of safety margin (RSM) for use in the areas of the global factor of safety, reliability and limit states analyses with reference to their respective allowable criteria. An equation for calculating RSM based on the reliability index is formulated. Efforts for proving the applicability of this criterion include a theoretical demonstration in a simple one-variable case; an investigation on a test problem involving two random variables, followed by a slope stability study on a 156 m high embankment dam and an illustrative example presented in a EuroCode 7 guidebook. Calculation of the ratios of safety margin in the three areas provides a quantitative way to accommodate the analytical results within the same theoretical framework and makes the outcomes mutually comparable and supportive, which is much more enlightening than that would be the case by considering only one of them. Calculating RSMs for reliability and limit states methods has also helped solve the key issue concerning the uniqueness of the partial factors calibrated from a particular ‘target case’. |

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.
