This makes it important to understand and appreciate the different types of structural systems that go into tall building structures. 2 Type of Structural
Tall Building Structures: Outrigger systems: In this structural system, the load-resisting core is located at the centre of the building, but has outriggers extending outward from the centre. This sort of system can hold up to 150 floors.
Tall Building Structures: Exoskeleton structural system: In this structural system, an ‘external skeleton’ is used to provide the building with load-resisting structure. The term exoskeleton is taken from biology, where some creatures have an external skeleton that protects the animal’s body (as against us humans, as we have internal skeletons).
Tall Building Structures: Diagrid system: A word derived by combining the words ‘diagonal’ and ‘grid’, this technique uses a framework of diagonally intersecting metal, concrete and wooden beams. This innovative structural system made it possible for engineers and architects to envision buildings that didn’t need to have columns, thus giving rise to a number of innovative and spellbinding designs.
Tall Building Structures: Tube system: In this type of structural system, the building is designed as a hollow cantilever that is placed perpendicular to the ground. The tube system brought in a huge leap in the heights of skyscrapers around the world.
Tall building structures Shear wall systems: In this system, vertical walls act as the load resisting structure, usually located in the core of the building. This system of tall buildings can hold up to 35 storeys.
Tall Building Structures Rigid frame systems: In this system, the load-resisting system is made by interconnecting rigid connections. This type of system was extremely popular in the first phase of tall buildings, and can hold 20 – 25 storeys.
