5. C modeling

5.1. Characteristics of modeling

Straight beam modelled by 22 knots and 21 SEG2 elements of type POU_D_TG.

This modeling was added to test the influence of the type of beam element in question. Shear coefficients \(\mathit{AY}\) and \(\mathit{AZ}\) (\(\mathit{AY}\mathrm{=}\mathit{AZ}\mathrm{=}6\mathrm{/}5\)) correspond to a right cross section.

5.2. Characteristics of the mesh

Number of knots: 22

Number of meshes and types: 21 SEG2 (POU_D_TG), 2 POI1 (DIS_T_N)

5.3. 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).

5.4. Tested sizes and results

The reference values are non-regression values.
