Mat Foundation Design Spreadsheets

This suite of spreadsheets undertake the stability analysis and structural design of a rectangular mat foundation.

These spreadsheets analyse a user defined foundation with up to 32 loading points and calculate the bearing pressures transferred into the soil. This allows the designer to optimise the mat 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 in both X and Y directions, and for both sagging and hogging moments. This can be done with either a Rigid or Flexible analysis depending on the stiffness of the proposed foundation.

After the pad size has been set, the spreadsheets then calculate the design bending moments and the required reinforcement in both X and Y directions. 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 capacity of the foundation in both X and Y directions and for punching shear and checks whether the pad is adequately deep.

Then a summary page is created and a reinforcement drawing is generated to show the exact reinforcement arrangements which the designer has specified.

The suite includes a total of 4 spreadsheets;

  • A Rigid mat foundation design spreadsheet which analyses a mat foundation assumed to be Rigid. This is suitable for deep, small, heavily reinforced or lightly loaded slabs which can be considered to behave Rigidly.
  • A Flexible mat foundation design spreadsheet which analyses a mat foundation assumed to be Flexible using a Winkler foundation type analysis. This is suitable for thin, long or heavily loaded slabs which can be considered to behave Flexibly.

Both Rigid and Flexible spreadsheets are available to comply with either British Standards BS8110 & BS8004 or Eurocodes BS En 1992 & BS En 1997.
