Raft or mat foundations. The raft is modeled in safe software. According to the code of my country the width of design strips for isolated foundations is 1m. Generating pattern surface loads is easily done by safe with an automated option.

Design strips can be generated by safe or drawn in a completely arbitrary manner by the user with complete control provided for. Safe tutorial analysis design of pile supported mat foundation free download as pdf file pdf text file txt or read online for free. 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. Thus a one meter design strip will be drawn in both x and y directions on the foundation.

Mat or raft foundation is a large concrete slab supporting several columns in two or more rows. Example 8 3 4 see example 8 3 4 in textbook page 363. 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. 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. It is used where the supporting soil has low bearing capacity. Mats and foundations can include nonlinear uplift from the soil springs and a nonlinear cracked analysis is available for slabs. Safe tutorial analysis design of pile supported mat foundation.

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. Load path and transfer of seismic forces. About csi safe csi safe is a software tailored for the engineering of elevated floor and foundation slab systems. This report shows the structural design of the raft foundation.

Force on a pile eq on unloaded pile. All analysis and design are based on the aci code. 45 x95 x7 0 with top of mat 3 6 below grade.
