Comprehensive documentation and sketches to explain the
method of design are included within the template for ready
reference and use.
The design formulae used in the calculations are shown on
the screen and in the printed output.
The user and the checker can therefore verify template
output by hand calculations.
On the spot display of background design information on the

Instant data validation and help-information display to
avoid and reduce input errors.
Reinforcement Type: Grade 460 Deformed Type 1 or Grade 250
Plain Round bars
Partial safety factor for steel strength gm: 1.05 or 1.15.
Concrete grade: C30, C35 or C40
Section overall depth: 150 mm to 1000 mm.
Design crack width: 0.1 mm or 0.2 mm
Restraint factor for thermal & shrinkage movement: 0 to
Concrete Cover: 40 mm or more.
Bar size: 8 mm to 40 mm
Bar spacing: Bar-size + 20 mm to the lesser of 300 mm or
Formwork for walls and suspended slabs: Steel or Plywood
Temperature Falls: T1 (Range 5 to 70 deg C)
between the hydration peak and ambient plus T2 (Range 0 to 80 deg
C) due to seasonal variations.
Interactive Estimation of Temperature T1 for concreting in
the UK. Based on the
information in Appendix A.3 of BS 8007, this feature allows change
of OPC Contents, Section Thickness, Type of Section and Formwork
for this estimation.
Surface zones for concrete cracking control: Walls,
Suspended slabs, Top of ground slabs or Bottom of ground slabs
Database facility within the RC8007 file to keep
information for up to 500 sections via worksheet STORE.
Using a reference number in the range 1001 to 1500, each
section can be retrieved, changed and re-designed with ease at a
Auto Analysis facility via two columns in the Worksheet
STORE. One column
allows selection for analysis and the other selection for
printing. All SELECTED sections can therefore be analysed and or
their results printed by a mouse click.
After Auto Analysis, the database in worksheet STORE also
keeps design information on Applied Loading, Calculated Strengths
and Thermal Steel Requirements for each section.
The worksheet cells showing inadequate strength or
reinforcement becomes red in colour.
The adequacy of each section therefore becomes obvious at a
The worksheet STORE is a visible Database of up to 500
sections. New data
can be generated and existing one examined and or modified using
usual spreadsheet features.
The template has virtually no user interface.
The A4 size Printed Output matches the Screen Display.
Knowing the use of Excel 97 and the ability to verify the
output as a designer is sufficient for using RC8007.
Shaded cells in the spreadsheet mean "User Input"
and un-shaded cells "Spreadsheet Results".
This permits easy checking at a glance both by the user and
the checker of RC8007 output.
