When the load-bearing capacity of the soil is low, the requirement of more area under the individual footing. Types of Combined Footing. Rectangular Combined Footing. Trapezoidal Combined Footing.
Combined footings are constructed for two or more columns when they are close to each other and their foundations overlap. Design of combined footings with example is discussed. The function of a footing or a foundation is to transmit the load form the structure to the underlying soil.
