Impressed vibration

The Caesar results give several modes of vibration starting from 1, 2.887, 4.351, 5.23, 5.809, 7.055, 9.047 Hz etc.

2 cases were modelled.

1. with the ineffective (supports that were taking any load because of loss of contact), actual at site.
2. with all the supports effective.

However during the dynamic run it was noticed that the very same supports that were actually ineffective have lifted off. In other words the natural frequency results are the same.
