It is very difficult to model the soil-structure interaction problem. In RCC buildings slab on grade is a very common construction system e. For safe and economical design, compute plate displacement and stresses accurately. Difficult to obtain samples for testing producing results in accordance with ground behavior.
Necessary to make simplifying assumptions. Scope Of Study To develop a workable approach for analysis of plates on elastic foundations. Structural Engineers go for simplified assumptions of rigid foundation STAAD Pro is used to incorporate the elasticity of soil that will provide approximate solutions as close to the exact solutions.
Types of Foundation Models The plate-foundation system is idealized as a thin elastic plate resting on a linearly elastic foundation. Various foundation models were given by the investigators which are discussed ahead. The deformations outside the loaded area were neglected and taken as zero. Winkler foundation model has two major limitations: No interaction between springs is considered.
The spring constant may depend on a number of parameters, such as stiffness of beam, geometry of beam, soil profile, and behavior. Top ends of springs connected to a elastic membrane stretched to constant tension T. Assumed that the plate deforms in bending only. Connecting the ends of springs to a beam or plate consisting of incompressible vertical elements, which can deform only by transverse shear. This model considers both the bending and shear deformations.
Modulus Of Subgrade Reaction Pressure sustained per unit deformation of subgrade at specified deformation or pressure level.
Beams on Elastic Foundation (Spreadsheet)
The exact solution for the governing differential equation of the problem is obtained based on the beam-on-elastic foundation approach in which the soil reaction on the pile is related directly to the pile lateral deflection. In this investigation, the modulus of subgrade reactions is assumed to be constant along the pile depth. Parametric study through numerical examples is carried out to prove the validity and accuracy of the obtained results. In general, the derived displacement field can be used to study pile response in multilayered soil profiles by subdividing the pile into a number of elements.
