4.8.3. Multi-Support Excitation PatternΒΆ
-
pattern
('MultipleSupport', patternTag) The Multi-Support pattern allows similar or different prescribed ground motions to be input at various supports in the structure. In OpenSees, the prescribed motion is applied using single-point constraints, the single-point constraints taking their constraint value from user created ground motions.

Note
- The results for the responses at the nodes are the ABSOLUTE values, and not relative values as in the case of a UniformExciatation.
- The non-homogeneous single point constraints require an appropriate choice of constraint handler.
