MEMBER DESIGN METHOD AGAINST IMPULSIVE WAVE PRESSURE CONSIDERING APPLICATION TO ACTUAL DESIGN

Abstract

 The design method for impulsive wave pressure with very short duration time is unknown, though there is a possibility that the members will be destroyed by tsunami. In this study, first, we conducted a regular wave experiment on large-scale and apply the results to our proposed design method. Then, the evaluation standard to actual design was proposed by approximating the cumulative distribution of the case where the deformation occured by the Weibull distribution. Next, we conducted a solitary wave experiment and the results were applied to the Weibull curve and confirmed to be consistent. Finally, a method for estimating four parameters of impulsive wave pressure by solitary wave was shown.
