..., it is not always clear to figure out appropriate seismic motions from the design points of views. The uncertainty effect on the response quantities is examined with the MCS method in the present study. Namely, uncertain parameters such as mean wave height, inertia coefficient, drag coefficient of Morison equation...

... by multiplying modification factors and the wave force based on Morrison's equation with the mean wave height and mean wave period. INTRODUCTION The dynamic response of offshore structures subjected to random wave forces can be computed by the random vibration analysis (Malhotra and Penzien 1970a), and its...

The ¢i is a random number with a uniform distribution, and n and T denote the mean wave height and mean wave period, respectively. If the sea surface motion is given by Eq.(2), the water particle motion at any depth can...

... height in parts of the North Atlantic. By the late 1980's there were sufficient years of wave measurements at a few locations in the NE Atlantic to suggest a statistically significant increase in mean wave heights. This suggestion, together with a widespread feeling that winter storms were getting more...
