A Reliability of Coastal Structures Under the Influence of Waves and Currents - Random Analysis of Fixed Structure - by Y. H. Choi, S. H. Kwon, D. W. Kim and S. G. Park Abstract This paper investigates the problem of random analysis of fixed structures, which are influenced by waves and current. Morison equation was employed to deal with the wave and current load. The wave kinematics are randomly generated from the wave spectrum. The necessary statistics and calculated from the resulting response time history. The simulation results are turned out to be very sensitive to the simulation technique.
