Triangulation is used in structures by incorporating triangular shapes or patterns within the framework, which significantly enhances stability and strength. This is because triangles are the only polygon that does not deform under pressure, making them ideal for resisting forces and distributing loads evenly

. Where triangulation is seen in a structure:

• In frame structures such as bridges, towers, and roofs, diagonal members connect vertical and horizontal components to form triangles. For example, the Eiffel Tower and communication towers use extensive triangulated frameworks to resist wind and other lateral forces

• In head frame structures, diagonal braces create triangular shapes that prevent deformation by evenly distributing forces, making the structure more rigid and stable

• Triangulated facades and shells in modern architecture use networks of triangles to provide both structural support and aesthetic appeal, as seen in geodesic domes and buildings like the Burj Khalifa

How triangulation makes the structure stronger:

• Triangles maintain their shape and do not collapse or distort when forces act on them, unlike rectangles or other polygons that can deform into parallelograms under stress

• By forming triangles, the structure distributes loads across all three sides, reducing stress on any single member and preventing bending or twisting.
• This rigidity helps structures resist lateral forces such as wind, seismic activity, or uneven loads, improving overall durability and safety

• In engineering, triangulated beams (reticulated or braced beams) allow for longer spans without the need for additional supports, making constructions lighter and more efficient

In summary, triangulation is used in structures by integrating diagonal bracing to form triangles within the frame, which stabilizes the structure by evenly distributing forces and preventing deformation, thereby making the entire framework stronger and more resilient
