The popular RC-spreadsheets package has been revised following the recent amendment to the UK National Annex to Eurocode 2 in December 2009. Version 4 of the spreadsheets provides for rapid production of design calculations to Eurocode 2 and the UK NA. The RCC series of spreadsheets have also been modified: they are suitable for design calculations to the now withdrawn BS 8110 (up to and including Amendment 4).

V4 formally introduces:

• TCC 15 Axially loaded walls/slabs

• TCC 55X Axial Column Shortening: 24 storeys

• TCC 62 Retaining Wall

• TCC 63 Core Wall Design and

• TCC 94 Two Way Slabs
