Instructional materials complementing fema p 751 design examples. The raft is modeled in safe software. Mat or raft foundation is a large concrete slab supporting several columns in two or more rows. Safe tutorial analysis design of pile supported mat foundation.

Slab modeling analysis and design procedures feature a suite of sophisticated tools and applications couple with post tensioning punching shear and beam detailing and integrate the influence of soils ramps columns braces walls rectilinear or curvilinear and other. Thus a one meter design strip will be drawn in both x and y directions on the foundation. Design of raft foundation page 8 2. In this special project the method used in the design called the.

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. 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. These design strips in x and y direction are usually defined in safe software as layer a and layer b. The bearing capacity increased by combining all individual footings in to one mat since bearing capacity is proportional to width and depth of foundations.

Raft foundation can be design using several methods. Force on a pile eq on unloaded pile. A raft foundation also called a mat foundation is essentially a continuous slab resting on the soil that extends over the entire f. According to the code of my country the width of design strips for isolated foundations is 1m.
