The reinforced concrete design spreadsheet (RCC11) is a program built to design reinforced concrete elements to BS8110. It was developed by the reinforced concrete council. The spreadsheet can be used to design slabs, beams and columns.
For slabs, the design moments needs to have been calculated prior to design. Slabs can be designed as simply supported, continuous or cantilever.
The same goes for beams; design moments need to have been calculated prior to designing with spreadsheet. Beams can be designed as simply supported or continuous span.
Reinforcement for beam shear can also be calculated with the spreadsheet.
Columns can also be designed with this excellent spreadsheet. Axial loads and any moments needs to have been calculated prior to designing with the spreadsheet program.
This excel spreadsheet program will basically calculate amount of reinforcement required and check that all other conditions are met in accordance with BS 8110 code.
