The results of experimental modal analysis and finite element calculation of both platforms indicate that they exhibit not only bending vibrations in the x and y directions but obvious torsional vibrations of lower modes .

Both cores had a relatively low strength area at 140 cm followed by a high value at 150 cm . Although the weak lens at 72 cm is not as pronounced in the cores , there is a definite indication of lower strength at that approximate depth ...
