SDLL131 - Seismic calculation of a piping VVP.
Comparison Aster-SYSPIPE




Summary:

This test contributes to the validation of the operator of spectral analysis COMB_SISM_MODAL of Code_Aster.
The studied structure is a line of piping VVP subjected to an excitation multi supports. It is with a grid in
elements of right beam POU_D_T and curve POU_C_T.

The numerical reference solution is given by code SYSPIPE of FRAMATOME.

- Seismic Differentials Displacement
u=0,004m with the node N45 (crossed Br) according to the local direction U.
U results from axis X by a rotation of angle
=109,02° around axis Z.
This loading amounts applying ucos displacements
and usin along axes X and Y.
Several cases of displacements are mentioned in the note of calculation FRAMATOME [bib1]
but only one is retained in this test.

Summary of the results
The answers obtained with the two codes are very close. Variations surplus not 1% on
primary and secondary components. More important differences are observed in
elbows. The latter are modelized with a curved element in SYSPIPE and 4 elements
POU_C_T in Code_Aster.
