v2.02.147 SDLL147 — Simple vertical beam mounted on a spring subject to an earthquake

Summary:

This test contributes to the validation of Code_Aster seismic spectral analysis operator COMB_SISM_MODAL. This is a non-regression test case, relating to the Gupta method, which considers both a dynamic and a quasistatic contribution of natural modes in a frequency band to be defined beforehand.

The structure under consideration is a simple vertical beam mounted on a spring. The values tested are the displacements, absolute accelerations and nodal reactions in 4 knots.
