1.A tall elastic structure that rests on the ground, consisting of small cross-sectional columns and beams, will never topple over, because their trunks do not have the necessary force to rotate it.
What will happen is the bases of the columns will remain glued to the ground, while the cross-sections of the beams and columns around the nodes will first elastically and then inelastically bend and break.
See first photo
2.A tall rigid structure made entirely of reinforced concrete such as prefabricated houses has the potential to topple.
See second photo.
3.A high rigid structure made entirely of reinforced concrete such as prefabricated houses, if it is placed on the foundation ground with ground anchors, will neither break nor topple.
and costs half the money. Simple things to beat the earthquake and bring the cost down.

Hi Ioannis Lymperis,
The assertion that a tall elastic structure will never topple because the columns and beams do not have the force to rotate it oversimplifies the complex dynamics of seismic behavior. While it's true that elastic deformation may prevent immediate toppling, the structure's response to an earthquake involves a combination of translational and rotational movements, influenced by factors such as the natural frequency of the structure, the ground motion characteristics, and the damping properties of the material.
Furthermore, once the structure reaches its inelastic deformation stage, failure mechanisms like buckling, shear failure, or even plastic hinge formation at the joints can lead to partial or complete collapse. Proper seismic design must consider these potential failure modes to enhance the ductility and energy dissipation capacity of the structure.
Thank you
Dear Selase A. K. Kpo
I have another philosophy which includes everything except for inelastic failures
Method Elastic or Dynamic Response?
