Dynamic Analysis of Deep Beams on Vlasov Foundation
In the present study, higher-order shear-deformable theories have been used for the dynamic analysis of deep beams on Vlasov foundation. For modeling the subsoil, the modified Vlasov model is used. It considers shear strain in the soil and gives a dish-shaped deflection for a uniformly distributed load on the beam. The values of the modulus of the sub-grade reaction, k, and the shear parameter, 2t, are computed using the properties of the soil. The modulus of elasticity and Poisson’s ratio of the soil is assumed constant from top to bottom i.e. from ground surface to top of the assumed rigid base. A Matlab code is developed and convergence study is carried out and then some realistic cases of loaded beam on elastic foundations are solved to determine the dynamic response like displacements, velocity and acceleration. The results, thus obtained, are compared, with the available results obtained by other researchers.
