The intensive condition in which the walls at the height of a building are in when they are subjected to lateral inertia stresses originating from ground acceleration the mass and multiplied by the height of the building is called bending.
During bending stresses, bending moments are developed which cause the wall to bend and create stresses within its frame.
So when we refer to bending we mean both the developing stresses and the deformations, also called bending arrows.
Walls in addition to bending are elastically inelastic and buckling.
The bending and overturning of the walls creates bending moments at the nodes and all the cross-sections that make up the walls bend elastically at first, then inelastically and finally sagging. The inelastic and fishy collapse of structural elements in very large earthquakes today is inevitable.
My applied research, primarily among other things, aims to make the walls more rigid more dynamic and irreversible in order to stop the inelastic and fishy bending deformation of the cross-sections around the nodes, thus preventing the inelastic and fishy deformations of the structures that bring them down.
To increase the dynamics and stiffness of the walls, apply pre-tensioning to their cross-sections with tendons at all ends.
To prevent them from overturning, prestress tendons of the walls are embedded in the foundation soil using strong expandable embedding anchors placed at the drilling depth.
The compaction caused by the expansion of the soil anchors and the filling of the boreholes with reinforced concrete contribute to the maximum bearing capacity of the soil.
Simulation and experiments with and without this method have shown that the load-bearing capacity of the structure with respect to seismic displacements is significantly improved.

Dear Samy Elhadi Oussadou
Yes, it's not something that's not in the literature. We all know what pre-stretching and grounding does.
Columns are elastic and have no dynamic response. The walls are stiff and dynamic. But they download large moments to the base and break the connecting beams.
Tensioning the wall frames and bearing on the ground prevents large moments at the nodes and bending moments at the wall frames, since compression kills tension and the contact with the ground prevents the wall from turning.
