Analysis of Different Shaped Footing Under Soft Soil Condition : A Review

Abstract

Soil Structure interaction is very important part of a building-load distribution. As the total load of a building is directly transmitted to the soil beneath footing. Shape of footing plays a vital role in distributing load to the soil, thus shape of footing should be ideal to distribute maximum load to the soil. Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics. The term footing or footings is an ambiguous one that can be interpreted in a number of ways. In some cases ‘footings’ is used as a synonym for shallow foundations. Shallow foundations are typically used where the loads imposed by a structure are low relative to the bearing capacity of the surface soils. Here, the most commonly used term is strip footing (or footings), referring to a strip foundations, used to provide a continuous strip of support to a linear structure such as a wall. Approved Document A of building regulations defines minimum widths for strip footings based on the load of load-bearing walling they support. A brief review on footing flexibility and code provision of previous studies is presented here. This literature review focuses on sloping ground, lateral forces in reinforced concrete structures, soil data implementation in a building foundation and some code provisions will be addressed by area.
