Effects of diffraction and directional asymmetry of random wave loads on a long structure

Abstract

In this study, we consider diffraction effect in analyzing wave loads on a long structure. When waves are obliquely incident on a long structure, the diffracted wave give forces on the lee side of the structure. Thus, the wave loads increase with the existence of diffracted waves and also the phase difference between the incident and diffracted waves. We further consider directional asymmetry effect in analyzing wave loads on a long structure. The force reduction parameters were analytically derived and verified with experimental data.
