| Abstract | This paper discusses the numerical methods that were developed for calculating the buckling loads with the corresponding buckled shapes of linearly tapered columns laterally restrained by multiple elastic springs. In formulating the governing equation of the column, each elastic spring was modeled as a discrete Winkler foundation of the finite longitudinal length. By using this model, the differential equation governing the free vibration of the column was first derived, which was subjected to an axial compressive load, after which the differential equation governing the buckled shapes of the column was formulated using the relationship between the natural frequencies and the loads. The Runge-Kutta method was used to integrate the differential equation, and the determinant search method combined with the Regula-Falsi method was used to determine the eingenvalues, namely, the buckling loads. In the numerical examples, clamped-clamped, clamped-hinged, hinged-clamped and highed-hinged end constraints were considered. The numerical results including the buckling load parameters and the buckled shapes of the columns were presented in non-dimensional forms. |

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.
