NcV for Shallow Foundations – Documentation
What this module does
This module calculates undrained vertical bearing capacity of shallow foundations as a function of foundation geometry, soil shear strength profile and foundation-soil interface conditions. This module also returns parametric studies demonstrating the sensitivity of bearing capacity factor over a range of embedment ratio, soil strength heterogeneity ratio and foundation-soil interface roughness.
Limits
This module operates within specified limits of dimensionless groups defining foundation-soil interface roughness, embedment ratio and soil strength heterogeneity. Limits are shown in parentheses in italics next to the parameter.
Usage
Select and fill in the desired input fields. Default values are provided initially. Hover over the input parameter for a definition of the term.
Click Submit and results will be displayed in the derived input, output and plot boxes. Hover over any derived input or output parameter for a definition of the term.
How to operate plots (using Plotly)
See: Zoom, Pan, and Hover Controls in Plotly Graphs
