Response of slender vertical cylinder under breaking waves

Coastal and offshore structures consist of slender cylindrical member as the fundamental component. Breaking wave loads are significantly important now a days due to calamities and disasters occurring in ocean environment. Structural damages and failures are catastrophic due to wave impact and it is necessary to understand the influence of breaking wave impact on the structural members. The standard codal provisions of breaking wave impact on structural members is scarce, it is essential to understand the physics of the interaction of breaking waves on structural members. In the present study, an experimental investigation has been carried out to measure the response of the slender vertical cylinder under breaking waves due to constant amplitude spectrum. The structural response of the vertical cylinder under constant amplitude spectrum was found from the measured acceleration. The deflection of the vertical cylinder due to breaking wave impact from acceleration measurements were found out by using omega arithmetic method. The acceleration and deflection are found to be maximum for both severe and moderate plunging events. The maximum deflection observed for severe plunging event is nearly 0.1m for the present study.
