The "Analysis"serves to verify the and of a footing. can be performed in the frame. The verification can be performed either for individual loads or the program finds the most critical one (can be selected from a combo list).
For both limit states (strength, usability) program assesses the. The value of the maximum allowable eccentricity of foundation is entered in the left part of frame.
The analysis is performed according to the selected type of field tests in the frame "", where is also chosen in the case of using CPT tests.
The analysis can be performed for the worst field test, the average from all tests or selected test from a combo list.
Further it is necessary to enter a safety factor for bearing capacity. It is recommended to use a SF=3 for all methods using CPT or SPT tests.
The stress in the footing bottom used for settlement analysis can be reduced by the geostatic stress given by:
- original ground
- finished grade
- not specified
In the case of inclined footing bottom or analysis according to the φ in the footing bottom.it is also necessary to enter an angle of internal friction
When calculating bearing capacity from the SPT tests (), the correlation for saturated fine or silty sands can be used.
Detailed listing of the results is displayed in the right part of the desktop. Visualization of results can be adjusted in the frame "".
