Large Span Structures-Concrete & Steel
Structures, with span larger than 20 meters, are generally considered as, Long Span Structures.
Structures, with span larger than 20 meters, are generally considered as, Long Span Structures.
Such structures if built in regular RCC construction the size and cost of structural members would be very high and hence an alternative construction technique is adopted.
Long span structures can create flexible, column-free internal spaces, better services co-ordination, better visual connection and can reduce substructure costs and construction times.
They are commonly found in a wide range of building types such as factories, warehouses, exhibition halls, indoor and outdoor stadiums, airport hangars, large shops, public halls, railway stations, bridges.
Their primary functions are, similar to normal roofs, typically, protecting against the weather, restricting the spread of fire, providing sound and thermal insulation and so on. However, as they may offer the only structural system other than the perimeter walls, they may also have to provide support for building services, access routes, lifting equipment.
Large Span Structures can be designed in Steel as well as Concrete.
