Uniform Excitation Pattern
The UniformExciatation pattern allows the user to apply a uniform excitatation to a model acting in a certain direction.
The command to generate a multi-support excitation contains in { } the commands to generate all the ground motions and the single-point constraints in the pattern. The command is as follows:
| pattern UniformExcitation $patternTag $dir -accel $tsTag <-vel0 $ver0> |
| $patternTag | unique tag among load patterns |
| $dir | direction graound motin acts |
| $tsTag | tag of the TimeSeries series defining the acceleration history. |
| vel0 | optional, the initial velocity, default=0.0. |
NOTES:
- The responses obtained from the nodes for this type of excitation are RELATIVE values, and not the absolute values obtained from a multi-support case.
