3.1. Characteristics of modeling#

This modeling containing only 2 elements is insufficiently refined to allow a good representation of the first 6 modes. However, it is retained in this test case for comparison with other codes as indicated in guide VPCS.

3.2. Characteristics of the mesh#

Number of knots: 3

Number of meshes and types: 2 SEG2 (POU_D_E), 2 POI1 (DIS_T_N)

3.3. Modeling parameters#

Response on the first 3 modes without static correction (combination of modal responses DPC)

Response on the 6 modes (combination of modal answers DPC, CQC, DSC duration: \(5s\))

Response on the first 3 modes with static correction of the 3 neglected modes (combination of modal responses SRSS)

Quadratic combination of directional responses (QUAD).

3.4. Tested sizes and results#

The reference values are the averages of the results of the compared codes, as well as non-regression values for the calculation with static correction.

3.5. notes#

Spectrum value (interpolation):	Mode	Mode	1	2	3	4	5	6
