Compressing-Bending Deformation of Base-Slab of Dry-Dock Settling Basin Resting on Elastic Foundation

Abstract

This research deals with the bending deformation resulted from the longitudinal-transverse forces on the dock settling basin bottom resting on
elastic foundation. Subgrade reaction coefficient of the contact problem is presented as a third order parabola which is computed by Fuss-Winkler
model and fourth order ordinary differential equation. The general solution of this equation is possible by considering the values of boundary
conditions and Maclaurin’s series method. The main characteristic of this method is using of the zero values as one of the boundary conditions
values and derivatives of Y(x) that gained by successive integration. Some equations are represented to compute the values of bending moment,
shearing force and deformation at any arbitrary point of the settling basin bottom section. A new method of computing the rate and quality of the
dock settling basin deformation is presented in this research. The results are compared to the results of the some other researchers.
