Dry-stone walls control (The rebuilding of Japan Earthquake and Tsunami regions)
People of Inca civilization were masters of the polished ‘dry-stone walls’, called ashlar, where blocks of stone were cut to fit together tightly without any mortar. The Incas were among the best stonemasons the world has ever seen, and many junctions in their masonry were so perfect that even blades of grass could not fit between the stones.
Peru is a highly seismic land, and for centuries the mortar-free construction proved to be apparently more earthquake-resistant than using mortar. The stones of the dry-stone walls built by the Incas could move slightly and resettle without the walls collapsing, a passive structural control technique employing both the principle of energy dissipation and that of suppressing resonant amplifications.
By studying the three movements of earthquakes (up /down)(left/right)(diagonal up/down) and the intensity of earthquakes on different types of bricks, I can even find out the centre of gravity of every brick, and redesign the entire brick wall using 3D design by using algorithms to calculate for unique bricks that form together that is so strong it can withstand a 10 digit scale earthquake, but the binding material cannot be cement, it will be locked together by steel devices that link the centre of gravity together of all blocks that is so strong it cannot be dislodged. – Contributed by Oogle
