εo = 0.00543228 Analysis Assumptions and Modeling Notes
Enough elements are selected so that the same model can be used to adequately characterize the dynamic
analysis. Prestress effects are turned on during the static and modal solutions.
The subspace method for eigenvalue extraction is chosen solely for the sake of completeness in this manual.
Other methods would also be suitable. Only the first three modes are requested. Results Comparison
