CONCEPT OF TUBULAR DESIGN IN HIGH RISE STRUCTURES

Abstract eng:
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 multi-storeyed 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. The various loads such as dead load, live load and wind load are assigned using software. Analysis of the structure has been done using software. The components of the structure such as the slab, beam and column has been designed by manual calculations. The slab is designed as continuous slab. The load calculations for slab and beam are done manually. The load for column design has been obtained from staad analysis report. The pile foundation for the bundled tube structure has been designed. The two main components of pile foundation are pile and pile cap. The design of pile and pile cap has been done by manual calculations. The pile has been designed as a square pile. The design detailing of all the designs such as beam, column, slab, pile and pile cap has been made in Auto-cad.
