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.
Safe 12 mat foundation.
Mat raft foundation modeling input check for soil pressure punching check deflection check.
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.
Raft foundations are suitable for medium rise story buildings ranges from four to twelve stories.
Raft foundation is one of the types of foundation that is composed of a thick mat or slab that supports the entire structures.
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.
This type of foundation is used when there are larger column loads to support and when soil bearing capacity is too low.
A mat foundation spreads out under the footprint of the building and declines the contact pressure compared to conventional strip or trench footing.
Safe is the ultimate tool for designing concrete floor and foundation systems.
Cohesionless soil in cohesionless soil a mat foundation does not fail in shear.
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.
From framing layout to detail drawing production safe integrates every aspect of the engineering design process in one easy and intuitive environment.
Raft mat foundation is used in those places where we have less bearing capacity of the soil.
These partial safety factors are specified in the design code of your country.
