Application of the Goda pressure formulae for horizontal wave loads on elevated structures
Abstract Small-scale physical experiments were conducted to investigate the application of the Goda wave pressure formulae modified to predict the horizontal wave loads on elevated structures considering non-breaking, broken, and impulsive breaking waves. The air gap defined as the vertical distance from the still water level to the base of the structure played a key role in the reduction of wave impact forces. Physical model results using random waves confirmed that the modified application of the Goda wave pressure formulae provided a good estimate of the horizontal forces on elevated structures for both broken and impulsive breaking waves. As the air gap was increased, the resulting forces decreased, and the estimated values became increasingly conservative. When the ratio of the air gap to water depth, a/h′, increased from −1.0 to 1.5, the reduction in force was approximately 75% when the wave height to breaking water depth ratio, H/h b , was equal to unity.
