The Analysis Of Convergence Of Finite Element Method For A Foundation Slab On The Bilinear Subgrade

摘要

This article considers the convergence of the foundation slab finite element model. Slab works in conjunction with the subgrade. In PC Cross Scad authors conducted combined calculation of the foundation slab and ground, based on the use of an iterative algorithm. Analytical research of convergence of the calculations results allowed selecting optimum partitioning step of the model. Conclusions drawn on rationality of calculations of the foundation slab on the bilinear subgrade realized in PC Cross Scad.
