Abstract:
We designed a six and a ten storied buildings in a same area (15m X 7.5m) and also in a
same seismic zone. We have followed the ACI code, UBC-1994 and BNBC-2006 to build
up the structures. We have endeavored our best and put an end of our project. We have
used ETABS Software for design purposes. The design process of structural planning and
design requires not only imagination and conceptual thinking but also sound knowledge of
science of structural engineering besides the knowledge of practical aspects, such as recent
design codes, bye laws, backed up by ample experience, intuition and judgment. The
purpose of standards is to ensure and enhance the safety, keeping careful balance between
economy and safety. Generally, a building structure is the combination of column, beam
and slab. The detailing of these are done by Auto CAD.
We found out the steel quantity of them and clarify the difference of required steel for two
buildings. We have find out the quantity of steel which is required in a floor and also
costing of steel for both buildings. In terms of column at first floor 336kg more
reinforcement is needed for ten storied. For beam this value is 820kg and for slab it is
1656kg. We have gotten 77.10% more reinforcement required at first floor for ten storied
buildings and it should be usual practice. In amount there are 212,400 BDT more need in
terms of ten storied building at first floor.
