Presenting new models to determine subgrade reaction modulus (Ks) for optimizing foundation calculations in coarse grained soils

Abstract Subgrade reaction modulus (Ks) is one of the most important soil parameters to perform structural calculations and analysis. Ks directly affects the determination of dimensions and reinforcement of foundations. Therefore, its exact and accurate determination is of significant importance in...
