Abstract:
Many studies on the distribution of contact pressure have been made when a flexible or rigid footing is founded on soil. Many investigators have proposed bearing capacity theories assuming the footing to be rigid. But all theories have been based on the assumption that the footing will always be in contact with the soil. In this paper numerical analysis is carried out to separate foundations with partial contact with soil form those with full contact. The factors determining the contact of footing with the soil are plan dimensions, thickness and elastic properties of the material of the footing, modulus of sub grade reaction of the soil supporting it, the column to footing width ratio and eccentricity of loading. The conventional method of finding bending moment says that the maximum bending moment is independent of the relative rigidity of the footing(i.e . thickness of the footing and the modulus of sub grade reaction of the soil supporting it). But ANSYS 12.0 results show that bending moment depends on relative rigidity of footing also. Experimental work have been conducted to verify the values of maximum bending moment given by ANSYS.
