The large-scale experiments described herein were carried out at Forschungs-Zentrum Küste (FZK), Hannover (Germany) by a research team of the Universities of Bologna, Edinburgh, Southampton, Plymouth, HR Wallingford and the Coast and Harbor Engineering, Inc. (USA). Wave-induced loads on close-to-prototype jetties were measured. Experimental evidence indicates the presence of force peaks with a short space–time correlation structure, carried by convective processes with a velocity of the order of the wave celerity. The important limitations imposed by the imperfect spatial resolution of pressure transducers on the integrated force are discussed. The finding may be of interest to design laboratory tests involving rapidly-varied processes such as impact waves and the subsequent analysis phase, which may lead to gross errors in the evaluation of the integral process. A guideline to select the cutting frequency is provided
The large scale experiments described in this paper were carried out at the Large Wave Flume (GWK, Große Wellenkanal) in Hanover (Germany). The research team included Universities of Bologna (IT), Edinburgh (UK), Southampton (UK), Plymouth (UK), HR Wallingford (UK) and Coast & Harbor Engineering Inc (USA). Wave-induced loads on close-to-prototype scale jetties were measured, with particular attention to scale effects due to air content in water. The aim of the paper is to present the tests, describe the impact process and give preliminary results concerning uplift loads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
