摘要：

The influence of depth taper on the frequencies of free torsional vibrations of a bi-symmetric I-beam with a constant flange width is investigated. The effect of various taper ratios and length-to-depth ratios is analysed for the first three modes. The problem is analysed by the finite difference method and the finite element method. The effect of shear deformation is also taken into consideration. © 1994.
