Better Mechanical Characteristics to Your Buildings

These images illustrate the idea behind the ELESDOPA patent. First two conventional walls are shown, a horizonatal and a vertical wall. The horizontal wall has a very low inertia moment Ix=(bh^3)/12=260.4 but a large contact length L=25. The vertical wall, on the other hand, has a good inertia moment Ix=(bh^3)/12=6510.4 but a small contact length L=5. The ELESDOPA patent has the advantages of both of these walls: a good inertia moment Ix=2[(bh^3)/12+bh*d^2)] = 6635.4 with a large contact length L = 25. All three stuctures shown have equal mass and therefore the material cost is the same.

ELESDOPA double-wall or multiple-wall elements achieve a higher second moment of area than the traditional walls while using the same amount of material. The deflection of a structure under load is smaller for higher second moments of area. Therefore, ELESDOPA walls deflect less than traditional walls when a load is applied.

The principle of optimizing the second moment of area of structures is well known and has been used in other fields of engineering. A famous example is the I-beam, used in steel constructions and as the rails for trains. The ELESDOPA patent applies the same physical concept to concrete walls resulting in excellent mechanical properties. These figures show how the second moment of inertia of an ELESDOPA wall is higher compared to traditional walls.
