Newmark's Influence Chart is an illustration used to determine the vertical pressure at any point below a uniformly loaded flexible area of soil of any shape. 8 Aug One can find out the stresses for the rectangular, circular or strip loading using the boussinesq's equation, but Newmark's influence charts were. Newmark () developed influence charts to compute the vertical stress (and also the horizontal and shear stresses) due to a loaded area of any shape.

5 Oct Use of Newmark's Influence Chart. Newmark () developed influence chart to determine the vertical stress due to loaded of area of any. Newmark's influence chart Newmark\us Influence Chart is an illustration used to determine the vertical pressure at any point below a uniformly loaded. Newmark's influence chart is developed from Boussinesq's equation. Boussinesq's equation considers a point load on a semi-infinite, homogeneous, isotropic.
