摘要

In this research the analysis of foundation is efficiently accomplished by using the pure displacement-based finite element method; it should be noted that the effect of the concrete column dimension in the connection place of column to foundation is examined with the aid of finite element method. It is possible to interpret the finite element method as a method of substitute loadings or load cases in the same boundary situation. To meet this objective, single foundations with square shape are analyzed for more than 50 different point loads at the center of the slab. The structural layer is used to define slab geometry, load and boundary conditions which are related to analysis only. At the time of analysis, the object-based model created by the authors converts into a finite element model, called the analysis model. The finite element mesh used in the analysis is a rectangular mesh, based on a maximum acceptable element size. The stress and displacements in a soil mass due to applied loading are considered in this paper. The authors found that the single footing settlement and stress of soil depend not only on physical and mechanical properties of base soils but also on applied load intensities and the size of the column connected to single foundation, as well as on footing and column rigidity, shape and dimensions. Based on the obtained results, it can be stated that by increasing in the load size (column size) the value of maximum stress and deformation in the soil of under foundation will increase.
