Influence of Moment on Load-Settlement Behaviour of Circular Footing Resting on Clayey Soil
Foundations of certain structures are subjected to large moments and relatively small vertical and horizontal forces. Moments on the foundation base are mainly caused by horizontal forces acting on the structure. It tends to tilt the footing. This tilt increases with the increase of load eccentricity, and consequently the bearing capacity is reduced. Short bored pile or pier foundations are widely used in situations where moment-carrying capacity is the dominant design requirement. But such foundations are very costly, and it cannot be adopted for small structures. Published literature on the moment-deformation behaviour of shallow foundation is very scarce. This paper investigates the influence of moment acting on the structure, on the settlement and angular distortion of the footing by carrying out a series of laboratory scale load tests on model circular footing in clayey soil. The parameters varied are magnitude of moment, magnitude of vertical load, depth of foundation, etc. Finite element analyses are also carried out, and the results are compared with those obtained from laboratory studies for validation. It is observed that tilt increases with increase in moment initially and thereafter decreases. It is also observed that tilt decreases with increase in depth of footing. Moment acting on the structure influences the load-settlement behaviour, and also, load-settlement behaviour improves due to the addition of reinforced foundation bed below the footing.
