摘要：Uplift pressure is said to be a design load that areconsidered for those structures which are constructed below the groundwater table level. If the depth of the excavation is deeper, then, the greater will be the upward pressure applied by the water.Uplift pressure is also known as hydrostatic uplift. It is better defined as the upward pressure that is applied to the structure, which in turn has the potential to raise it relative to its surroundings. While constructing a structure it should be designed properly so that it can provide greater resistance against the uplift forces in order to avoid risks due to the occurrence of water pressure. So, while designing, the uplift pressure must be taken into consideration since maintenance and rehabilitation of foundation is not possible to be carried out easily in the future. Also, the parameters such as bearing capacity of soil, type of loading, location of footing etc. affect the stability of the footings in different mechanisms. In this paper, the modelling and analysis of a 12 storied building which are supported by different footings is been studied. The modelling and analysis of the building is done using Extended ThreeDimensional Analysis of Building System software. Whereas, the modelling and analysis of different footings are carried out using CSI SAFE finite element analysis package for slabs and foundations. Various parameters such as the internal force, bending moment, shear force, footing stress are determined. The behavior of footings in terms of the parameters are evaluated. The results are then compared.
