**v2.02.149** SDLL149 — Seismic calculation of pipe BM3 (test NRC)
========================================================================

**Summary:**

This test mainly makes it possible to validate the implementation of method GUPTA (correlation between periodic and rigid parts of a modal response) on a seismic calculation by spectral method applied to a portion of pipes (COMB_SISM_MODAL).

Other methods are also evaluated on the same configuration:


* SRSS,


* CQC,


* CQC with pseudo-mode.

This test was proposed by NRC to validate the seismic design of nuclear installations.
