Power is invisible and only shows its effects when the balance of power is lost. The force is deflected in different directions. A civil engineer who designs a load-bearing body consisting of slabs, beams, columns, and walls directs the forces to the ground to balance the forces with the ground reaction. This is 100% ensured when the structure is at rest, since all forces are directed towards the ground and equilibrium occurs. When the earthquake starts it is not the same. In the earthquake, many forces are developed in the load-bearing elements of the structure, which are directed upwards. For example, a wall that receives the lateral inertia of the structure at its height, would topple if it did not have the beams to hold it. When rocking the structure, the wall rotates the beam once up and once down with force. If the strength of the beam is strong it will withstand this stress and if not it will break. To make the beam strong enough to withstand the moments it receives, we place 1) many hoops (ductility) 2) increase the strength of the concrete, 3) reduce the cross-section of the reinforcement (not the reinforcement) But still if the earthquake (acceleration ground) is large and with duration the measures we designed are not able to bring the balance of the forces and the beam breaks. If we increase the dimension of the cross-sections of the beams, we increase the inertia, so it is a free gift. Cliff front and stream behind. Is there a solution so that we can build strong projects at every earthquake acceleration, and for what duration? We said that in a state of rest all forces are directed towards the ground, while in an earthquake other forces are created which are directed upwards (due to moments) I am the first person in the world to propose that the upper ends of the walls be bolted to the foundation soil, in order to receive the upward forces arising from the overturning moment of the wall, and send them into the soil, preventing them from being directed upwards to the beams and break them. This is a revolution dear civil engineers and I want you to take my proposal seriously to defeat every major earthquake. We will also lower the construction cost because we will reduce the steel reinforcement, and we will create a strong foundation due to compaction.
