Abstract. This research examines transient vibrations in concrete structures that are strengthened with nanocomposite reinforcement, focusing on graphene oxide-carbon nanotube (GO-CNT) materials to improve the mechanical properties and dynamic response of concrete. A 3D shell theory of elasticity is employed to model the interaction between the nanocomposite material and concrete matrix during dynamic loading. Hooke's law is included to describe the linear elastic behavior of the materials, while viscoelastic foundations and mechanical stress are illustrated to include the effects of damping and foundation stiffness on the dynamic response to vibration. Using the unified solution method, acceptable displacement functions are derived to characterize the deformation response of the system under transient loading. The `Rayleigh-Ritz` approach is utilized to simplify the problem; meanwhile, the Lagrangian energy function is established to describe the energy status of the system. The governing equations are solved by applying the inverse Laplace transform technique to develop time domain responses from the frequency domain. The results represent the dynamic behavior of concrete structures reinforced with `GO-CNT` nanocomposites that will lead to developments in concrete construction. This study contributes to the understanding of vibration behaviors of reinforced concrete with nanocomposites while illustrating a case for the use of modern materials and novel methods to increase the efficiency of a structure.
