The case that the vibration of the plumbing becomes a problem exists often in the facilities such as the actual plant, and there is a possibility that the non-linear vibration caused by a gap between the restraints and plumbing occurs. A resonance curve is one of the important characteristics of the non-linear vibration, and the establishment of the calculating method is significant. However, the difficulty of the analytical process, in the non-linear vibration of elastic beam becomes a problem. We have been proposed the analytical and computational method to calculate the Backbone curve of an elastic beam. We propose here the simplified analytical technique to calculate the resonance curve in the non-linear vibration of elastic beam with gap support. The validity of the proposed calculation is verified in comparison with the resonance curve from experiments. The calculated result well follows the experimental ones.
