Varying Soil Properties in RISAFoundation

While RISAFoundation has a Default soil properties (Subgrade Modulus and Allowable Bearing), it is possible to create regions of varying soil properties.

Varying soil properties 1

This can be achieved by applying additional Soil Regions to your model. Simply select Soil Regions from the Insert menu, enter in the differing soil properties, and draw in the region. When completed the soil region will be displayed in orange.

Please also note that a Soil Region may be used to model a location where there is no soil resistance. For example, if you have a portion of your foundation that does not bear on the soil, you can use a Soil Region drawn under that portion to model the gap. Simply set the Subgrade Modulus to 0 and the Allowable Bearing Pressure to something very small (since the program will not allow a zero input):
