Analysis and design of foundation for RCC structure wth varying soil strata

Abstract

As time goes by, the development in the construction industry all over the world is progressing. Many structures are being built, both residential and non-residential, as well as roads and bridges. Foundations of any building or structure shall be designed and constructed to withstand safely all the dead, imposed and wind loads without impairing the stability or inducing excessive movement to the building or of any other building.When designing foundations for a structure there is a need to determine the bearing capacity of the underlying soil on which the foundations will be laid. This applies to all forms of foundations from a simple isolated footing to complex raft and pile cap foundations.The minimum investigation involves testing the bearing capacity of the supporting ground beneath a proposed building. This must be carried out by a suitably qualified professional or certified testing firm prior to the design of foundations. The method of testing varies depending on the sub- surface conditions. The type of ground and its bearing capacity determines the foundation requirements.
