8 for this example. Example 8 3 4 see example 8 3 4 in textbook page 363. Staad foundation advancedwill use the imported geometry and support reactions to design a mat foundation for the structure. You will use staad pro us example no.

At those places we use mat foundations to distributes the whole loads of the structure to the soil when the area of the footing was increase than the soil load bearing capacity will also increase because this foundation reduces the stress on the soil at the same place.

It is used to support storage tanks industrial equipment silos chimneys and various tower structures.

Example a mat foundation is to be design by the conventional method rigid method for the loadings shown in fig. All columns are 40x40cm ultimate soil bearing pressure q ult 100kpa f yk 300mpa f yd 300 1 15 260 87 mpa c25 f ck 20mpa f ctk 1 5 mpa. Compensated foundation the net pressure increase in the soil under a mat foundation can be reduced by increasing the depth d f of the mat. Mat foundations are constructed on various occasions such as building construction bridge construction tower construction etc.

A mat foundation is a thick reinforced concrete slab supporting arrangements of columns or walls in a row or rows and transmitting the loads to the soil. This approach is generally referred to as the compensated foundation design and is extremely useful when structures are to be built on very soft clays.
