4. B modeling results#

4.1. notes#

This modeling is done to test option PLAQ_POUT_ORTH of the key word liaison_elem of the affe_char_meca command.

4.2. Characteristics of modeling#

Figure 4-b: Detail of the mesh around the edge and center posts.

The mesh is a bit different from that of modeling A. The column axes are respected, but a border of ½ column width is added to the slab. Other modeling choices are possible.

4.3. Natural frequency calculation#

The frequencies are given in \(\mathrm{Hz}\).

Mode

Frequency \(\mathrm{HZ}\)

1

1.83439E+00

2

2.73610E+00

3

3.10015E+00

4

5.51120E+00

5

8.73582E+00

6

8.94514E+00

7

1.00630E+01

8

1.58920E+01

This modeling is a non-regression test, so the frequencies should not be compared to those obtained by the other codes.
