Application of the Goda Pressure Formulae for Horizontal Wave Loads on Elevated Structures

다국어 초록 (Multilingual Abstract)

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