Tridilose

The tridylose is a system that consists of a highly light three-dimensional structure and a mixed board, combining the compressed zone of concrete (concrete) with the tensile zone of steel. It was invented in 1966 by the Mexican engineer Heberto Castillo.

In Peru, tridylosas gained special importance due to the Peruvian engineer Miguel Bozzo and the specific calculation methods using finite elements developed by his son, the engineer Luis Bozzo in 1986. A summary of the work and methods of Tridilose calculation can be found in the book 'Mixed Reticular Slabs. Project, Analysis and sizing" written by Miguel Bozzo and Luis Bozzo in 2003 and published by the Reverte publishing house in Barcelona, Spain.

In tridilose, only 33% of the concrete works by compression, with an efficiency of up to 90% of this material, which allows the construction of much lighter, stronger and more economical structures in much shorter times than conventional systems....

The Tridilosa has been used in more than 200 bridges in Mexico, in the World Trade Center of Mexico City, the Chapultepec Tower, Siglo Medical Center XXI, Plaza Cuauhtémoc, Plaza Tabasco 2000, Hotel Morelia Misión and in the Biosfera 2 building (Arizona, USA)

One of the most outstanding qualities of its structure is that it can save 66% of concrete and up to 40% of steel, due to the fact that it does not need to be filled with concrete in the traction zone.

Tridilose is used not only to make ultralight roofs and bridges (in Nicaragua, Castillo built a bridge over which trucks pass, which can be lifted by 2 men, one at each end), but also floating docks and even pangas, like those that sail in Campeche^{[citation required]}.

It is also used for special solutions such as aviation hangars, department stores, office buildings, hotels, among others^{[citation needed]}.

In Mexico there are almost a million square meters built with Castillo's invention. At one time it was thought of using tridilose to erect the discussed PEMEX tower in Mexico City, but the idea was discarded so as not to give publicity to one of the critics of the state oil monopoly^{[citation required ]}.
