Stationary oscillative experiments of the cylindrical liquid storage model by the shaking table have been carried out, in order to confirm the validity of the results of the theoretical analysis as shown in the foregoing paper in detail. In the theoretical analysis, the nonlinear effects of the boundary condition on the free surface of the inner liquid are mainly investigated. From the result of the numerical calculation of the stationary oscillative problem, it has been clearly pointed out that nonlinear responses, whose circumferential wave number n = 0 or 2, occur at the frequency region in the neighborhood of the first resonance point. In the present paper, confirmation of the appearance of such nonlinear responses has been almost completely done, where dynamic behavior of the wave elevation have been recorded by the high speed video system and the other time dependent data, that is, dynamic liquid, pressure at the side wall, acceleration and displacement of the base of the model tank, have been put into A/D transducing procedures. Experimental results of both stationary components of dynamic liquid pressure and maximum wave elevation have been arranged in the form of the backbone and resonance curves, arid compared with that of the foregoing theoretical analysis. Both of these results turn out to have relatively good agreement, in which nonlinear bi-harmonic responses and super-harmonic resonance phenomenon at the frequency in the neighborhood of the first resonance point have been certified both theoretically and experimentally.
