Abstract
This project provides some fundamental background of the European Structural Codes
(Eurocodes) and some introductory aspects particularly on design principles and the
differences with British Standard Codes brought about by the harmonised codes. This
project also investigates and compares the use of BS 8110 and Eurocode 2 in the design
of reinforced concrete flat slab to determine the differences between the two codes for
this project. The scope of this research is designing principles for slab design by using
the Equivalent Frame Method. The loading and analysis are taken from the slab structure
that is loaded with track trench, analysed and detailed design results made based on the
analysis results. The building adopted for this project is a factory building; the
Scandinavian Industrialised Building System (SIBS) Precast Building Components
Factory. The building is a one-storey building consisting of ground floor with steel deck
roof. The ground floor consists of production and storage area. The building is about 5m
high having an approximate plan dimension of 110m x 46m. The British Standard Design
reinforcement bars strength and unit weight of reinforced concrete are slightly less than
that of Eurocode 2 Design. The result of concrete cover needed for Eurocode 2 Design
is more than that of British Standard Design due to more fire resistance characteristics.
The reinforcement area for both span middle strip and column strip as well as support
middle strip and column strip of British Standard Design is less than that of Eurocode 2
Design. However, the British Standard Design using BRC A10 wire mesh need to
provide full yield strength lap length causing the reinforcement area provided increases
to 569.9 mm2. The cost of concrete needed for Eurocode 2 Design is higher than that of
British Standard Design based on the designed concrete cover thickness. Lastly, the cost
of steel reinforcement bars needed for Eurocode 2 Design is lower than that of British
Standard Design according to the designed steel reinforcement bars area provided.
