Shallow foundation construction example. A shallow foundation is a type of building foundation that transfers structural load to the Earth very near to the surface, rather than to a subsurface layer or a range of depths, as does a deep foundation. Customarily, a shallow foundation is considered as such when the width of the entire foundation is ...
Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. [1]
Karl von Terzaghi was the first to present a comprehensive theory for the evaluation of the ultimate bearing capacity of rough shallow foundations. This theory states that a foundation is shallow if its depth is less than or equal to its width. [ 4 ]
Shallow foundation. Shallow foundations are used where the loads forced by a structure are low relative to the bearing capacity of the surface soils. Deep foundations are needed where the bearing capacity of the surface soils is insufficient. Those loads need to be transferred to deeper layers with higher bearing capacity.
In the United Kingdom most subsidence claims are for buildings at least 40 years old with shallow strip foundations. This is one of the most common types of foundations suffering from subsidence-related damage and according to the Building Research Establishment subsidence database, mass concrete underpinning was the most common underpinning ...
It is a component of a shallow foundation. [1] Wall Footing. Wall footings carrying direct vertical loads might be designed either in plain concrete or in reinforced concrete. Since a wall footing deflects essentially in one way, it is analyzed by considering as a strip of unit width and its length.

A strap footing is a component of a building's foundation. It is a type of combined footing, [1] consisting of two or more column footings connected by a concrete beam. This type of beam is called a strap beam. It is used to help distribute the weight of either heavily or eccentrically loaded column footings to adjacent footings. [2]
