The transfer matrix method is presented to study the vibrations of any pretwisted nonuniform beam of rectangular cross-section. The frequency equation is derived and expressed in terms of the transfer matrix. The corresponding results are compared with previous work in the literature. Finally，the influence of pretwisted angle and taper ratio on the natural frequencies is investigated. S.Y.LEE 李森墉 1999 學位論文 ; thesis 40 zh-TW
