The triangle is the only polygon that does not deform when a force acts on it, which is why it is used regularly in construction. It is a simple structure formed by bars, which gains rigidity thanks to its shape.
We can find them everywhere, on pylons, on cranes, in tents , on some bridges, on fairground rides and in some buildings.
Based on triangulation, beams of considerable length and resistance have been achieved, called reticulated or braced beams, widely used in the construction of large buildings that require large flown areas and without pillars, achieving greater resistance than solid beams.
Steel and Wood are the most used materials in the construction sector. Mainly steel is the one that is used the most in Spain, due to its high resistance, low cost, speed of assembly and its ability to be reused.
There are many famous structures that are made up of triangles joined together :
- The Eiffel Tower (Paris, France), 300 m high.
- The Millennium Wheel, the London Eye (London, United Kingdom), a 135 m Ferris Wheel.
- The Golden Gate Bridge (California, United States).
- The Polyhedral Reticular Dome F-12, for the Dalí Theater-Museum in Figueras (Girona).
As we have seen, Steel is a very resistant material and allows the manufacture of light structures.
