Nowadays, composite beams have found increasing popularity in the structures due to their proper features. Previous studies did not address the effect of structural damping to analyze the vibrations of composite curved beams. Therefore, in this study, semi-analytical and finite element methods are developed to consider the damping effect in vibration analysis. Furthermore, a framework is presented to study the composite curved beams with variable cross-sections considering the effect of different parameters such as geometric parameters, boundary conditions, and fiber orientation which has been compared with commercial software ANSYS. The results show that the present method can well predict the behavior of the beams.
