| Abstract | Indian seismic code design procedure, which permit the estimation of inelastic deformation capacity of lateral force resisting systems, has been questioned since no coherence exists for determining the values of response reduction factor tabulated in code. Indian code at present does not give any deterministic values of ductility reduction factor and overstrength factor to be used in the design, because of the inadequacy of research results currently available. Hence, this study focuses on the variation of overstrength and ductility factors in steel moment resisting frame with different seismic zones and number of story. A total of 12 steel moment resisting frames were analyzed and designed. Response reduction factor has been determined by performing the non-linear static pushover analysis. The result shows that overstrength and ductility factors varies with number of story and seismic zones. It is also observed that for different seismic zones and story, ductility reduction factor is found to be different from overall structural ductility. It is observed that three buildings of different heights had an average overstrength of 63% higher in Zone-II as compared to Zone-V. These observations are extremely significant for building seismic provision codes, that at present not taking into consideration the variation of response reduction factor. |

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.
