Concept Version 3
Concept V3 is an invaluable tool for the conceptual design of
reinforced concrete frames which enables the comparison and
determination of the optimum structural solution. It assists with
concrete frame choice, member sizes and reinforcement estimates.
V3 is now available free of charge!
Concept V3 provides an extremely fast way of
helping to choose between different concrete frame options for a
multi-storey scheme design. It can be used for time and cost
comparisons and gives initial member sizing, quantities of
formwork, reinforcement and concrete - all useful information when
making a choice of frame.
Spans up to 12m (16m for wide beams) are
catered for. Information such as the number of bays, spans, and
load is simply entered. Cost and time data, and many of the base
assumptions may be changed. The program sizes up and compares
conceptual designs to Eurocode 2. Within 5 minutes, 13 forms of
reinforced concrete frame construction can be considered then
ranked in order of total or construction cost.
Concept V3 will automatically choose the best
cost-optimised scheme from the following forms of reinforced
concrete frame, or allow the user to investigate their preferred
- Flat slabs
- Post-tensioned flat slabs
- One-way slab, wide beam One-way
slabs (X and Y)*
- Ribbed slab (X and Y)* (c/w
- Troughed slabs (X and Y)*
- Precast hollowcore and in-situ
beam (X and Y)*
- Two-way slabs
*Spanning in X and Y direction
Alternatively, the automatic choice can be
over-ridden, allowing alternative solutions to be investigated.
As it is spreadsheet, much of the program's
work and data is available for inspection, avoiding the 'black box'
scenario. The engineer can then proceed with verification and
detailed design in the normal way.
Printed outputs include floor plans, sections,
isometric stick diagrams, cost comparisons and material quantities.
A construction cost summary can also be produced, based on default
rates for construction costs or those put in by the user.
Once the structural frame has been decided the
engineer may then use the suite of RC Design Spreadsheets for
How to use the software
Open the file concept.xls using Microsoft
The spreadsheet uses macros, so you must
‘enable macros’ when asked.
If you cannot enable macros you should change
your security setting within Excel as follows:
Click Tools-Macro-Security and set the
security level to ‘Medium’ and restart Excel.
The welcome sheet gives instructions for use,
but the following should be noted:
- Cells containing blue text are
for data entry.
- Values in red or with a red
background indicate errors.
- Do not copy and paste from one
cell to another – this may cause errors.
- To get started, press ‘Start’ in
the welcome sheet, and then use navigation area to proceed though
the design stages.
