M. To assign a foundation support
To automatically model a support using foundation parameters, use the following procedure.
STAAD.Pro can take foundation parameters for footings or mat foundations and automatically model spring supports.
- Select the nodes that will have the same support condition.
Specification ribbon tab, select the
Foundation tool in the
The Create Support dialog opens to the Foundation tab.
Foundation type to model:
Direction of the resistance of the spring
The directions X, Y, or Z generate a spring in that global direction. The other two global directions are fixed against translation and moment about the selected direction is also fixed. The directions X Only, Y Only, or Z Only generate a spring in that global direction only.
- Type the Subgrade Modulus of the soil.
- (Optional) For Elastic Mat or Plate Mat foundation types, check the option Print influence area of each joint to include this information in the output.
Elastic Mat or
Plate Mat foundation types, select a nonlinear
spring option if necessary:
Option Description None linear springs are generated Compression Only generated springs are compression only (made inactive if in tension) Multi-Linear generated springs can have a multilinear displacement-spring constant curve associated with the mat foundation
To… Do the following… add the support type to the model and assign to the current node selection click Assign. add the support to the model for later assignment click Add.
