Civil Engineering/Tie Beam load in Foundation


The load of walls resting on tie beams is directly transferred to the soil below right? but some engineers take the load of tie beams and walls on foundation. So what is the correct method?

Hi Ghulam,

This is a complex subject as it depends on soil/structure interaction and the relative stiffness of the ground beam, the wall above, as well as the soil. It also depends on the wall geometry and whether it has any door/window openings.

For example, if the wall is solid (without openings) and is framed by the ground beam, the ring beam at the top and columns at both sides, then by virtue of arching action the majority of the load will be transferred to the foundation pads on the 2 sides, but again that is assuming that the length: height ratio is not much more than 2.5 to 3. Any longer than this will cause the ground beam to carry more load, which will either transfer some of the load to the ground or else span to the pads either sides depending on relative stiffnesses mentioned earlier.

If you want to play it safe, take say 80% load onto the basis and 60% onto the beam/ground. There is some duplication here, but that is the only quick solution unless you do a detailed soil/structure/settlement analysis!
