Analysis of strip plate on elastic foundation using a generalized subgrade model
Asrat Worku, Amlesu Tewoldebrhan
In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: A generalized subgrade model is presented by Worku (first author) for subgrades idealized an elastic layer overlying a rigid base. By implementing this model a governing differential equation of strip plate on elastic foundation is formulated. A closed form particular solution of infinite and finite strip plate, when using winkler type and Kerr equivalent Pasternak model are obtain by using different boundary conditions under different loading conditions. A finite element based Plaxis 2D software is used to calibrate the subgrade models. A numerical illustration is provided using this model in comparison with Plaxis 2D models. The result show that the calibrated variants give a good results in agreements with finite element outputs .consequently, the calibrated models can be used in routine analysis of strip plates on elastic foundation and can be incorporated in commercial software.
