ECONOMIC CONCRETE FRAME ELEMENTS TO EUROCODE 2

info:
This publication is based on design to Eurocode 2 and updates the original pre-scheme sizing
handbook Economic Concrete Frame Elements which was based on BS 8110 and published in 1997.
Eurocode 2 brings economies over BS 8110 in some areas – up to 10% has been reported. While
sizes of frame elements to BS 8110 would generally be safe, they would be sometimes unduly
conservative and uneconomic in increasingly competitive markets. In addition, current British
Standards for structural design are due to be withdrawn by 2010, with BS 8110 Structural use
of concrete being made obsolete in 2008. Thus this new edition of Economic concrete frame
elements has been produced by The Concrete Centre.
The new charts and data have been derived from design spreadsheets that carry out design
to Eurocode 2 and, as appropriate, other Eurocodes, European and British Standards. The
methodology behind the charts and data is fully explained and is, essentially, the same as that
used for the previous version of this publication. However, the following should be noted:
• For continuous members, sizes are derived from analysis which, in the case of in-situ beams,
includes the frame action of small columns.
• A new method for determining the sizes of perimeter columns is introduced. This takes
account of both axial load and moment.
• Generally, in line with BS EN 1990 and its National Annex, loading is based on 1.25Gk +
1.5Qk for residential and offi ce areas and 1.35Gk + 1.5Qk for storage areas.
• Much of the economy over the charts and data for BS 8110 comes from the treatment of
loads and defl ection by the Eurocodes – please refer to Defl ection in Section 7.1.2.
• Ribbed slabs are an exception. Compared with BS 8110 greater depths are required.
Readers are advised to be conservative with their choices until such time as they become familiar
with this publication and the workings of Eurocode 2.
