RC slab / wall design

RC Slab / Wall Design

Carry out strength/ULS and SLS checks based on flexural, twisting and in-plane effects, shear, stress limits, minimum and maximum areas of reinforcement and crack widths or spacing considerations for a large range of international Codes of Practice.


Model in-plane effects and calculate reinforcement arrangements for bridge decks with and without in-plane forces, tunnel linings, culverts, retaining walls, leaf piers, integral bridge decks, circular tanks and more.

New in Version 21

  • The use of a sandwich model based upon Annex LL of EN1992-2 (and CEB-FIP Model Code 1990) is now provided for use with BS 5400-4:1990, BS 8007:1987 and BS 8110-1:1997 and BS8110-2:1985 (UK), IRS:CBC-1997 (India), MOMRA Bridge Design (Saudi Arabia), NZS 3101-1:2006 and NZTA Bridge Manual v3.3 (New Zealand), SABS 0100-1 (Ed. 2.2) (South Africa) and SS CP65-1999 (Singapore).
  • For the existing supported design codes, which include those for USA, UK, India, New Zealand, Saudi Arabia, Singapore and South Africa, shear design checks are now included for BS 5400-4:1990, BS 8007:1987 and BS 8110-1:1997 and BS8110-2:1985 (UK), IRS:CBC-1997 (India), MOMRA Bridge Design (Saudi Arabia), NZS 3101-1:2006 and NZTA Bridge Manual v3.3 (New Zealand), SS CP65-1999 (Singapore) and SABS 0100-1 (Ed. 2.2) (South Africa).
  • Crack width calculations, for those codes which include them, can now be calculated at the concrete face or at the 'cover required for durability', giving additional control over the design check to avoid over-conservatism.
  • Detailed rendered calculations referencing clauses from design codes are available for all checks made for all design codes.

In detail...

Flexible reinforcing arrangements

Define multiple reinforcement arrangements for top and bottom (or near and far-face) layers for use in different regions of your model.



Refine your design and reduce waste from over-simplification of steel placement.


Allow for tapering and steps in sections.


Choose your results


Plot contours and values that indicate flexural reinforcement requirements at Ultimate Limit State (ULS).


Calculate design crack widths at Serviceability Limit State (SLS) for those design codes that support this.


Report, revise, repeat

Create design reports individually or append them to the report for the whole model. 


Mix summary reports for the whole structure with detailed reports for selected regions. 


Create templates to speed reproduction of similar content.

RC design checking of a circular tank wall

Watch as a circular tank is modelled from scratch and loaded with a water pressure load. A design combination is created and the RC slab / wall design facility used to carry out ULS design checks for a section of wall to the UK Eurocode.
