the five first vibration modes of the two considered beams, with a
variable cross section, obtained using the 2D-NNRPIM v2p1 formulation, are
presented.
5.4.3 Free Vibration of a Shear Wall
A shear wall with four openings is studied in this example. The geometrical
parameters of the shear wall are presented in Fig.
