Abstract | Modelling structures with discrete coordinates provides a practical approach for the structural vibration problems. The closed-form solution approaches for beams with arbitrary boundary conditions have been developed in the useful form of finite element suitable for inclusion in a computer program. Both the frequency domain analysis and the modal analysis are considered to evaluate the dynamic responses. The frequency-dependent shape functions of a beam element are obtained from the deflection function derived by solving the governing differential equation. Integration of the shape functions gives the element stiffness, mass and damping matrices that can be used to assemble the global matrices for the whole structure by the direct method as usual. Dynamic force may be separated into its harmonic components by means of a Fourier series expansion. Response spectra to general type of loading are presented. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
