Uplift Forces on Wave Exposed Jetties: Scale Comparison and Effect of Venting

Abstract

The large-scale experiments described herein were carried out at Forschungs-Zentrum Küste (FZK), Hannover (Germany) by a research team composed by the Universities of Bologna, Edinburgh, Southampton, Plymouth and the Coast & 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. After a 100 Hz sampling, forces on the deck bays and front induced by regular and irregular waves are analyzed, focusing the effects on the wave-in-deck loads of (i) wave irregularity, (ii) air venting and (iii) experiment scale in the evaluation of maximum and quasi-static loads. A comparison with the small-scale results is carried out, but differences could not be directly ascribed to scale effects only

Impact of focused wave groups on pier structures: a case study of severe breaking waves at Pont del Petroli during storm Gloria

“…The authors proposed expressions for impulsive and quasistatic wave forces where forces are made dimensionless through the use of the significant wave height H s , and identify linear trends between dimensionless forces and (η max -c l )/h toe , where η max is the maximum water surface elevation, c l is the deck clearance, h toe is the water depth at the toe of the structure. Similarly, in the work of Gaeta et al (2012) the modelled jetty consisted essentially of a rectangular plate attached to a heavy reticular steel frame. The model scale was 1:4 with fixed bottom.…”

Effect of Girder Spacing and Depth on the Solitary Wave Impact on Coastal Bridge Deck for Different Airgaps

“…Lamberti et al (2011) [12] carried out a large scale experimental study using regular and irregular waves on close to prototype jetties to deduce the wave-induced horizontal forces on the deck front, and they have evaluated the spacing of pressure transducers effect in obtaining impact force. Gaeta et al (2012) [13] extended the investigation by including the effect of wave irregularity, air venting and experimental scale factor. The above studies were further extended through numerical investigation (Gaeta et al, 2015 [14]) for wave breaking conditions while considering the air compressibility effect.…”
