Tridilosa
From Wikipedia, the free encyclopedia
Tridilosa is a highly light and resistant, material-efficient 3-D structure, made from steel and concrete and widely used in civil engineering, invented by the Mexican engineer Heberto Castillo.
Among the most remarkable features of this structure is that it can save up to 66% of the concrete used and up to 40% the amount of steel, due to the fact that it does not need to be filled with concrete in the tension zone, only in the superior compression zone. It is so light that it can float on water, but it is three times stronger than traditional construction flagstone. It was used, for example, to construct the 54-floor World Trade Center of Mexico City.
