- This tool is for evaluating bearing capacity of mat foundation in clay, as shown in the figure above.
- All the input parameters should be positive.
- The unit weight of water is 9.8 kN/m
^{3}. - For "nan", "0" or "inf" displayed in Results, please check your input parameters.
- Q is the allowable load (dead weight of the structure and the live load).
- If Q is given to estimate Fs, users can choose "Input Q to find Fs". If Fs is given to estimate Q, users can choose "Input Fs to find Q".
- Trial-error process can be used to estimate the dimension of the foundation (width,length and depth) for a given Q and a required Fs.
