چکیده

Abstract


Simulating shallow grid foundation resting on a homogenous C & / soil by different nonlinear finite element analysis types, and estimate the foundation geometry effects on choosing the nonlinear analysis accuracy and degree, will be the main two concerned points through this paper. Almost of the nonlinearity classified agent techniques were mentioned briefly. Through studding the interaction between foundation and soil where the expected penetration may occurs, small and large deformation analysis was performed with a good comparison between their results for various loading levels. The soil material nonlinearity was defined by hardening plasticity cap model while elasticity model was chosen for the foundation. Then the tested variables for grid foundation were performed again on a systemized rectangular raft foundation to discuss contrasts in relative stress distribution inside the soil for the two varied foundation geometries. ABAQUS cae V.6.9.1 was the F.E Program simulation.

6. Conclusions


In this study, the first objective is discussing the influence of analysis types ‘‘degrees of nonlinearity” on the behavior of grid foundation interacted with soil and spots on the grid beams attitude during the difference between beam lengths in the same grid.


The second objective is showing the difference demonstrated in the relative stress flow distributed under the center of rectangular foundation compared with the other under the same point in grid foundation, when the overall loads are the same, and found that when attending to study the ultimate loading case long deformation analysis and high degree of nonlinearity must be carried out.
