THE SPREADSHEETS

The RC-spreadsheets:v4 are intended to help with the rapid production of clear and accurate design calculations for reinforced concrete elements. These Excel spreadsheets are intended as aids for design to both Eurocode 2 and BS 8110-1:1997.

Version 4 sees the release of updates to the Eurocode 2 spreadsheets in line with amendment AMD 1 of the UK National Annex which was published in December 2009. It also formally introduces TCC15 Axially loaded walls/slabs; TCC55X Axial Column Shortening: 24 storeys; TCC62 Retaining Wall; TCC63 Core Wall Design and TCC94 Two Way Slabs. Whilst BS 8110 was ‘withdrawn’ by BSI early in 2010, it was recognised that some projects and indeed some practitioners may wish to continue using this standard in the short to medium term. Thus the RCC series of spreadsheets have been updated and are reissued. They are suitable for design calculations to BS 8110 (up to and including Amendment 4).

Eurocode 2 (BS EN 1992-1-1: 2004) was published in December 2004. The publication of its National Annex in December 2005 gave those Nationally Determined Parameters (NPD) to be used in BS EN 1992-1-1 in the UK. These standards together with the BSI document PD6687 allowed the suite of spreadsheets to Eurocode 2 to be finalised. Along with updates to the BS 8110 spreadsheets as a result of AMD 3 these were issued for general use as Version 3.

Since their release in January 2000, the RC-spreadsheets have proved to be enormously popular. They are written for engineers by engineers. The original spreadsheets have been maintained and may now be regarded as thoroughly tested by engineers in practice. The spreadsheets’ usefulness and robustness have been enhanced by users reporting problems or suggesting improvements. Registrants are periodically informed of available intermediate updates. Any comments or suggestions on the spreadsheets should be emailed to The Concrete Centre helpline@concretecentre.com or see www.concretecentre.com/rcdesign

The original Spreadsheets were produced under a DETR PiT research project by the Reinforced Concrete Council (RCC). The RCC was subsumed into The Concrete Centre which has itself been incorporated into the Mineral Products Association. Version 4 sees the re-branding of the spreadsheets.

LimitationsSpreadsheets can be a very powerful tool. They can save time, money and effort. They provide the facility to optimise designs and they can help instil experience. However, these benefits have to be weighed against the risks associated with any endeavour. Appropriate levels of supervision and checking, including self-checking, must, as always, be exercised when using these spreadsheets.

The spreadsheets should be used in compliance with the accompanying publication User Guide to RC Spreadsheets: Addendum for v4, which itself should be considered as an addendum to User Guide to RC Spreadsheets: v3

Licences The RC Spreadsheets are made available as shareware from The Concrete Centre see www.concretecentre.com/rcdesign However, the spreadsheets may not be used for commercial purposes until the user has purchased and validated a licence.

Licences may be purchased from The Concrete Centre website tel +44 (0)1276 606800. Licences may be validated via www.concretecentre.com/rcdesign

Further information, updates, FAQs, free trial download versions of some spreadsheets, latest news and other information on the RC-Spreadsheet suite is available on www.concretecentre.com/rcdesign

Using the spreadsheets for the first time The spreadsheets are Excel files, part of MS Office and may be copied to your preferred folder and accessed in the normal way through Windows Explorer or My Computer. Alternatively use Menu.xls. To run, load Menu.xls from within Excel, or double-clicking Menu.xls from within Windows Explorer or My Computer.

When loading Menu.xls, (or many other spreadsheets) you should be prompted about macros. If available, please click ‘enable’ (otherwise see ‘Macros’ below). When prompted about link updates in Menu.xls – please click ‘update’. Depending on machine speed, there may be some delay before the top sheet, containing conditions of use and basic instructions, appears. Click the BS 8110 or EC2 sheet tab as required. The individual spreadsheets may be loaded as required by clicking on the appropriate button. A fourth sheet provides a check on version numbers: the ‘update links’ macro used when loading is used to verify which versions are held in your folder.

Basic InstructionsBlue underlined cells are for data entry.

Red highlighted cells indicate entry errors or

Do not paste or drag data (destroys conditional cell formatting).Do not open an individual spreadsheet in more than one window (this may disable pull-down menus).

Help is available Within Excel under Help. To the right hand side of the spreadsheets, cells under 'Operating Instructions' contain help and error messages. From the User Guide. Files are included within the ADMIN folder within the RC Spreadsheets v4 folder. User

Guide to RC Spreadsheets: Addendum for v4, should be considered as an addendum to User Guide to RC Spreadsheets: v3. A copy of Adobe Acrobat Reader will be required to read this file.

Visit www.concretecentre.com/rcdesign for FAQs or to submit your query online. Contact The Concrete Centre’s helpline by email helpline@concretecentre.com. Most errors can be fixed by restoring the base version of the spreadsheet.

FAQ: MacrosWhen loading the individual spreadsheets, a Security Warning in Excel may warn about the presence of macros. All the macros provided in the files are either to allow automated calculation routines, automated printing of the ‘calculations’ or to provide choices by way of combo-boxes. The printing macros have been assigned to buttons. Turning the macros off will affect the function of some spreadsheets. Turning the macros off will also make printing of the sheets as configured difficult and make the choice of options very much more difficult.

If macros are not enabled on your system, within Excel click Tools/ Macro/Security and set your security level to “Medium”. Reboot.

FAQ: FontsFor correct appearance (especially of embedded graphics) ensure that the Marker and two Tekton fonts are installed. Your fonts may be checked by selecting Start (or Settings)/ Control Panel/Fonts, and viewing the font list.

Managing the spreadsheetsUsers and managers should be aware that spreadsheets can be changed and must address change control and versions for use under a QA procedure.Appropriate levels of supervision and checking, including self-checking, must, as always, be exercised when using

these spreadsheets.Spreadsheets demand an initial investment in time and effort - but the rewards are there for those who take advantage.Good design requires sound judgement based on competence derived from adequate training and experience - not just

computer programs.

UpdatesUpdates to v4 will be made available to licensed users via www.concretecentre.com/rcdesign If changes are significant registrants will be notified by email.
