本文探讨用于复合材料 /混凝土复合梁动力分析的一种等效非经典理论方法 ,给出了基本方程和一般解以及非经典理论效应系数 ,求得固有频率与振型等动力特性的解析解 ,从而为这类新型复合梁的工程计算提供一种较为简便而实用的计算公式。

An analytical method for the dynamic problems of FRP/Concrete composite beam, which is transformed to an equivalent homogeneous problem and solved by a non classical theory, is discussed in this paper. The governing dynamic equation, its general solution and the effect coefficient of the non classical theory are given. The analytical solution of dynamic properties including natural frequencies and modes is obtained, and a simple and practical numerical formula for the engineering application of the composite beams is presented.
