Abstract:	本文將C/sup 0/高階層梁部分應力模態有限元素法,應用於直交異向性材料積層梁之自由振動分析。與古典層梁理論及其修正公式比較,本法所得結果相當接近修正c/sup 1/高階層梁自然頻率理論解。將本文結果應用於不同型式積層梁之自由振動分析,由此歸納得積層梁自然頻率分析的一些重要結論。 The partial hybrid laminated beams element is applied to the free vibration analysis of orthotropic laminated beams in this paper. The kenetic energy is added to the modified Jing-Reissener principle. Through vibration, the element stiffness is the assembly of flexural stiffness in displacement version and transverse shear stiffness in hybrid version. The present element obtains accurate results, which approach the exact solution of frequencies based on the refined C/sup 1/ higher-order beam theory. Some important observations are also concluded on the frequency analysis of orthotropic laminated beams.
