.. _V2.02.017: **v2.02.017** SDLL17 - Large curved beam fixed on both ends ========================================================================= **Summary:** This study aims to perform a spectral modal analysis on a pipe network according to the input data specified in test No. 06 in document NUREG /CR-1677 BNL - NUREG -51267 vol.1 The pipe is modelled by Timoshenko beam elements with a circular cross section. The entire pipe is based on several elastic supports. The system is subject to a few point masses. .. image:: images/10000201000002810000021638483942C419489E.png :width: 3.8339in :height: 3.1937in .. _RefImage_10000201000002810000021638483942C419489E.png: The model and modal analysis are generated from module BEAM of salome_meca 2020 while the spectral modal calculation is done using Code-Aster. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Mod_lisation_A
