What is a concrete core in a building?

Concrete coring is the term that is sometimes used to describe the creation of a solid concrete building center. These can be used as security safes, safe rooms, or elevator shafts. Concrete cores in buildings can also provide a solid structure to build the remainder of the building.

What is lift core wall?

The lift core in a building is one means whereby one may travel from the level of one floor to another. RCC concrete core walls or steel frames with open sections are commonly used in practice as a lateral load resistant system for multi-storey buildings.

What is core and shell in construction?

Core and shell construction is a commercial building technique that is cost-effective and convenient for developers, contractors and tenants alike. The concept refers to building only the base structures of commercial properties before the building is rented out to a tenant.

Core and outrigger structural system Outrigger systems functions by tying together two structural systems (core system and a perimeter system), and render the building to behave nearly as composite cantilever. The outriggers are in form of walls in reinforced concrete building and trusses in steel structures.

How thick is a core wall?

Wall thicknesses of the core at the base of the building are 500mm for perimeter walls and 200mm for all other walls. In the upper levels the core is further assisted by a single shear wall constructed between units to connect the core to the facade.

Interior stairwells and the areas around elevator shafts generally are the strongest parts of the building.

What is core and shell in LEED?
