For example the bearing capacity of a raft foundation having a width of 6 m and founded to a depth of 3 m in a sand deposit having relative density corresponding to spt n value of 10 is about 700 kn m 2 which is extremely high.
Safe 12 mat foundation.
Safe is the ultimate tool for designing concrete floor and foundation systems.
It is a suitable solution for low bearing capacity soil spread footing cover about 70 of the structure high structure loads soft pockets or cavities of in the soil to unknown extent raft and.
These partial safety factors are specified in the design code of your country.
Raft foundations are suitable for medium rise story buildings ranges from four to twelve stories.
It can be considered on higher buildings depending.
We are committed to delivering uninterrupted software services worldwide during the covid 19 crisis.
Safe watch and learn video tutorials cover a wide range of topics from basic product overviews to advanced subjects such as post tensioned slab design.
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.
From framing layout to detail drawing production safe integrates every aspect of the engineering design process in one easy and intuitive environment.
This type of foundation is used when there are larger column loads to support and when soil bearing capacity is too low.
Tutorial videos safe important message.
A mat foundation spreads out under the footprint of the building and declines the contact pressure compared to conventional strip or trench footing.
Cohesionless soil in cohesionless soil a mat foundation does not fail in shear.
In the design code of my country the partial safety factor for dead loads for ultimate limit sate case is 1 3 and for serviceability limit state is 1 for the cases where there are only dead and live loads.
From framing layout all the way through to detail drawing production safe integrates every aspect of the engineering design process in one easy and intuitive environment.
Mat raft foundation modeling input check for soil pressure punching check deflection check.
