Extreme Wave Events
Results of a 1:10 scale physical model were used to determine the horizontal and vertical pressure distributions on an elevated structure for nonimpulsive wave conditions. These experimental pressure distributions at the time of the maximum force for nonbreaking waves were extracted for a range of structural air gap conditions and compared with pressure distributions defined by the equations of Goda (2010) and Wiebe et al. (2014). Predicted forces were generally conservative compared to measured mean or significant forces due to regular or irregular waves. A simple equation to determine the vertical force based on the bottom-most horizontal pressure was developed.
