IMPACT LOADS INDUCED BY PLUNGING BREAKERS ON VERTICAL STRUCTURES

R. Schmidt, H. Oumeraci, H.W. Partenscky

Abstract


Results of large-scale model tests on impact loading of a vertical wall by using waves up to 2 m height and 9.4 s period are presented. A classification of the breaker types tested and breaking criteria for waves in front of a vertical wall are suggested. Impact pressure distributions, forces and force impulses induced by plunging breakers on a vertical wall are discussed. The statistical distributions of the impact pressures and forces for different breaker types are also given. Some aspects of the generation mechanisms of impact pressures and the role of air content and its statistical distribution in the impact process are outlined.
