Validation of Ultimate Load Capacity Using Nastran on Hybrid Double Skin

Prajwal SR, Narayana B R, Dr. N S Kumar

Abstract: Analytical investigation was carried out on Hybrid double skinned steel tubular columns consisting of an outer and an inner tube made of steel, with space in between filled with the different grades of light weight concrete as infill. Analysis was done for the ultimate load carrying capacity of tube subjected to axial loading, including the failure pattern up to the ultimate load. Firstly, the models of the required geometry has been created in Hypermesh software and later on the model is exported to NASTRAN software where the model is made to run and to get accurate analysis result. Finally the obtained results are made to view in Hyperview where we get the desired (pu) values. Comparison for analytical and experimental results is obtained as presented in this paper. Composite sections are fetching progressively prevalent in construction. Coupling the strength of two diverse materials to form a composite section can be valuable in terms of both structural routine and price tag. A case in point of a far and wide used composite section in construction is composite column, this form of construction has turn out to be very widespread in modern years, where steel beam and concrete column act compositely to battle load.

Keywords: Hybrid double skinned steel tubular columns, light weight concrete, NASTRAN and Hypermesh software, Finite element analysis, composite column.
