2. Benchmark solution#

2.1. Calculation method used for the reference solution#

Modeling A:

Guide VPCS (not published): comparison with codes STRUDL, POUX,, SYSTUS, CASTOR, SAP IV [1].

For the comparison of method CQC, comparison with Castem2000.

B modeling and C modeling: non-regression

2.2. Benchmark results#

6 first natural frequencies and participation factors.

Displacements of points \(B\) and \(C\), nodal reaction at point \(A\) (response on 3 modes for combinations DPC and SRSS, response on 6 modes for combinations DPC, CQC and DSC).
