Geometry of Mat Foundation in Clay (bearing capacity)
Tips
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.
