Abstract:
This research concentrate on design a multi storey building consist of twenty storeys building by using manual calculations(BS81101997code) and computer programmes named Etabs and Safe according to different international codes such as: BS8110-1997, ACI-2005, Eurocode 2-1992. The building consist of flat slabs, columns, raft foundation, shear wall and staircases. Moreover, the comparison was made and it was found that: firstly, the area of steel for flat slab by using AC1-2005 is greater than the area of steel for flat slab by using manual calculations(BS81101997code) about 3% ,and greater than the area of steel by using both codes BSI8110-1997 and EC2-1992 codes about 1% . Secondly: the area of steel for columns by using AC1-2005 is greater than the area of steel for columns by using manual calculations(BS81101997code) about 0.2% ,and greater than the area of steel by using both codes BSI8110-1997 and EC2-1992 codes about 2%. Thirdly: the area of steel for raft foundation by using EC2-1992 code is greater than the area of steel in manual calculations(BS81101997code) about 29% ,and greater than the area of steel by using BSI8110-1997 code about 5% and greater than the area of steel by using AC1-2005 code about 3%.
