It could even exceed the construction of a pile foundations beyond a certain level. In addition, an increase in the axial loads ensures a higher cost for construction work.
However, with the increase of the loads, different methods that discuss in this article are introduced to enhance the stiffness of the slab.įurther, we could use raft foundations to support the buildings up to about 10 floors. Smaller the loads applied on the mat foundation, we construct a flat plate. There are a variety of designs based on the application of loads. Mat foundation is always not a flat plate place on the ground as the superstructure support. In this backdrop, we select the raft foundations. The increase of the dimensions of the footings further and further, cause overlapping the stress bulbs each other create the weak zone.
With the increase of the axial loads on the structure or due to the poor ground conditions, the area of the footings (isolated, combined, strip footing, etc) need to be increased. If we are dealing with the shallow foundations, the last option of the shallow foundation is a raft foundation. Mat foundations are constructed on various occasions such as building construction, bridge construction, tower construction, etc. Mat foundations also are known as raft foundations, is a thick concrete slab placed on the ground as the foundation of the structure.
