Actually when load is coming on any structure.
Load path from roof to foundation.
These elements define the mechanism of load transfer in a building known as the load path.
The load path extends from the roof through each structural element to the foundation.
Engineered structures are composed of multiple types of members that connect in order to move the loads from the top to the bottom of the structure.
The process starts at the top with the uppermost roof element tracing the loads down through the structure to the foundation.
Multiple elements are used to transmit and resist external loads within a building.
This video shows the load transfer from slab to foundation in a very detail way.
Load paths the economy and efficiency of the structure is improved by the following.
Vertical load path from roof to ground on a platform and pile construction building.
Involving fewer structural elements.
This effect is simply termed load path load paths need to be continuous.
The continuous load path from the roof to the foundation has to resist uplift pressure that can rip roofs away from walls shear forces in the walls that brace the building sliding forces that tend to push the house off the foundation and overturning forces that tend to tip the house.
Then structure will transfer.
Loads in any building have to travel from the roof and upper floors down to the ground.
Minimizing the load path to the foundation.
