• Multi-fidelity analysis for vibration is performed to develop a co-kriging model for uncertainty quantification.

• Euler-Bernoulli and Timoshenko beam theory is used as the low fidelity and high fidelity model, respectively.

• Kullback-Liebler divergence is used to quantify deviation between high fidelity and multi-fidelity models.

• Huge reduction in computer time for Monte Carlo Simulation is shown with the multi-fidelity co-kriging model.
