The "Bearing capacity" frame displays the results from the analysis of foundation soil bearing capacity. The stress in the footing bottom (assumed constant) is derived from all verifications performed in the frame "Verification". The programs "Spread footing" and "Spread footing CPT" then consider all verifications as load cases.
A restriction according to Fig. 4-4, page 73 of the NCMA manual is neither automatically enforced nor checked by the program. The bearing pad must be introduced into the program so it complies with the design criteria.
Three basic analysis options are available in the frame:
The input field allows us to specify the foundation soil bearing capacity. The results of verification analysis of soil for eccentricity and bearing capacity are displayed in the right part of the frame. The "In detail" button opens the dialog window that displays detailed listing of the results of verification analysis of foundation soil bearing capacity.
Pressing the "Run Spread footing" button starts the program "Spread footing" that allows for computing the soil bearing capacity or settlement and rotation of a footing. Pressing the "OK" button leaves the analysis regime - the results and all plots are copied to the program "Redi Rock wall". The program "Spread footing" must be installed for the button to be active. The overall length of the wall foundation is input.
The procedure is identical as if calculating soil bearing capacity by the "Spread footing" program.
The foundation soil bearing capacity is not computed.
The program allows us to specify a shape of stress in the footing bottom.
Verification can be performed in the place:
- bottom of leveling pad
- bottom of blocks
Visualization of results can be adjusted in the "Drawing Settings" frame.
