Concept Of Tubular Design In High Rise Structures

Multi-storeyed buildings are used for office, complex, residential flats, public centres, etc.There is need for multi-storeyed building due to overcrowding of cities.These multistoreyed buildings can be transformed into tall buildings in order to achieve more floor space but occupy less land space.In the design of tall buildings, lateral loads play predominant role.The lateral loads are wind load and seismic load.There are various lateral load resisting systems such as braced frame system, moment resisting frame system, frame truss-interacting system, shear wall system, core and outrigger system and tubular system.The tubular system comprises various types such as framed tube, trussed tube, tube in tube and bundled tube.In this project, a plan has been created for the bundled tube comprising four tubes using Auto-cad.
