How Loads Affect the Raft Foundation

[izmirlimuhendis]

In a project I was solving, I accidentally wrote -50 to the raft foundation elevation. However, when I analyzed it, I also saw that the solution does not give an error. How can a foundation that does not touch the building fail? How do we know if there is a load transfer in the reports?

I accidentally wrote -50 to the raft foundation level in a project I solved. However, when I analyzed it, I found that the solution did not give an error. How can a foundation that does not touch the building give an error. How do we understand whether there is a load transfer in the reports.[/ quote] Hi, If there is no load transfer to the raft foundation, the Calculation Moments of Static and Reinforced Concrete Calculation Reports will be zero or close to zero. At the same time, the minimum, average and maximum ground stresses will be the same or very close to each other in the Raft Foundation Soil Stress report. Apart from this, when the solid model is examined in the perspective window, a gap is seen between the superstructure and the foundation, the foundations are not visible in the vertical expansions of the columns.

There may be a raft that never touches the building. If you want to build a raft platform on piles on a swampy ground, you need this facility of the program. This is also the case with sap2000. It is the same in stages. It's always like that.
