Finite Element Analysis of frame with square meshing & radial meshing in Soil Structure Interaction
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2015, Vol 5, Issue 3
Abstract
Mostly structure is analyzed and designed assuming fixed support at the foundation level and hence effect of compressibility of soil under the foundation is ignored. The structure analyzed and designed in this way does not give the actual or realistic behavior. In actual condition the structure is generally supported on compressible soil mass. Present work is to study behavior of bare frame having soil beneath. In these cases three types of soils are considered, soft, medium stiff and hard. For the analysis of a building frame, the columns at the foundation level are considered as fixed. But in real condition it is not the case. While considering soil in the analysis of building frame 100% fixity may not be ensured. Because of the settlement and rotation of foundation, shear force and bending moment in superstructure get altered. This effect is called as “Soil Structure Interaction”. The soil domain is discredited by using square meshing and radial meshing. These cases are analyzed by using ANSYS 14.5 comprised between Square and Radial meshing for different extent of soil domain and presented to have results and conclusion.
