Results from wave impact tests are used to analyze the pressure distribution on a vertical structure with an overhanging horizontal cantilever slab. The structure faces two individual impacts, occurring sequentially on the vertical and horizontal parts. An expression is being proposed for the location of maximum pressures p(max) (z(max)) on the vertical part as a function of the wave steepness (H/L-0). On the horizontal part, p(max) is located at the attached corner of the structure. The relations between measured p(max) on the both vertical and horizontal parts and related rise times (t(r)) are analyzed and new non-dimensional functions are proposed. The boundary conditions for occurring of high dynamic pressures are determined both on the vertical and horizontal part. Three different pressure distribution cases are proposed as SBW, BW and BWSAT according to the breaker type. For each breaker type, the local pressure ratio's p(h3)/p(h1), p(h1)/p(v1), and p(h2)/p(v1) are analyzed, where p(h1), p(h2) and p(h3) are the local peak pressures at the SWL and top and bottom of the vertical part respectively, whereas, p(v1) is the local peak pressure on the horizontal part. Recommended profiles are calculated from local p(max) values. (C) 2012 Elsevier Ltd. All rights reserved.
