Mat Or Raft Foundation Ppt

Mat foundation often considered to be used when dealing with the following conditions.

Mat or raft foundation ppt.

Hydrostatic uplift resistance is needed etc. Determine the capacity of the foundation 2. Raft foundation is generally used to support structures like residential or commercial buildings where soil condition is poor storage tanks silos foundations for heavy industrial equipment etc. Design the structural component of the mat foundation using the stress distribution obtain from 4.

Raft foundation presentation ppt when to use raft or mat foundation in construction for building foundation design it is one of the most important aspects is to choose the right foundation. Here is the list of some of the major aspects when to use or choose a mat foundation. Then a waterproof plastic sheet is laid over the earth and a thin 3 layer of plain cement concrete pcc is poured just to create a perfectly flat and level base for the foundation. Such a footing is called a raft or mat foundation.

6 mat raft foundation 7 types of mat foundations 8 to design mat foundation. R a f t f o u n d a t i o n s 10. Usually mat foundation is spread over the entire area of the structure it is supporting. Determine the stress distribution beneath the foundation 5.

The spread footings cover over 50 of the foundation area because of large column loads. Mat foundation is also known as the raft foundation. The columns have high axial loads. Mat and pile foundation noroz fiaz malghani 2.

Working principle of raft foundation. The raft foundation is a kind of combined footing that may cover the entire area under the structure supporting several columns in one rigid body. The raft foundation is usually used with this kind of soil. It is a continuous thick concrete slab on the soil that extends the entire footprint of the building and increases the soil bearing capacity power.

How to construct a raft or mat foundation a raft foundation is constructed by first excavating the ground to a uniform flat level. It is use to support storage tanks industrial equipment s chimney s and various structure. Determine the settlement of foundation 3. Haque 2 shallow foundations are usually located no more than 6 ft below the lowest finished floor.

Raft or mat foundation. A shallow foundation system generally used when 1 the soil close the ground surface has sufficient bearing capacity and 2 underlying weaker strata do not. Determine the differential settlement 4. In this project the soil profile shows that the bearing stress is around 100 kn m2.

To design raft foundations. This foundation supports the entire building loads and safely transfer it to the ground. Mat raft foundation a mat foundation is a thick reinforced concrete slab supporting arrangement of column s or walls in a row and transmitting the load into the soil.
