This suite of spreadsheets undertake the stability analysis and structural design of an octagonal shaped single foundation.
These spreadsheets analyse a user defined octagonal foundation subject to axial, horizontal and moment loads.
Bearing pressures, overturning moments and sliding forces are calculated and graphically represented on three separate charts. This allows the designer to optimise the foundation dimensions to suit the loading arrangements and the maximum bearing capacity of the underlying soils.
After the pad size has been set, the spreadsheets then calculate the design bending moments and the required reinforcement. The designer can then specify the precise reinforcement arrangement using our unique Suggested Reinforcement Chart which shows graphically the available reinforcement arrangements which satisfy both required cross sectional area and spacing requirements.
Then the spreadsheets calculate the shear and punching shear capacity of the foundation and checks whether the pad is adequately deep.
Then a reinforcement drawing is generated to show the exact reinforcement arrangements which the designer has specified.
The suite includes a total of 2 spreadsheets;
Spreadsheets to complete the above designs in accordance with either British Standards BS8110 & BS8004 or Eurocodes BS En 1992 & BS En 1997.
