Abstract

The paper presents a design formula for Tetrapod armour on a 1:1.5 slope exposed to head-on random wave attack The formula predicts the relative number of broken Tetrapods as function of: the mass of the Tetrapods, the concrete tensile strength and the wave height in front of the structure. Thus, the formula addresses the observed problem of ensuring structural integrity of the slender types of non-reinforced armour units. The formula is based on results from small scale model tests with load-cell instrumented Tetrapods in which both the static, the quasi-static and the impact proportions of the loads were recorded.. The analysis follow the methods given in Burcharth (1993) and Burcharth et al .. (1994) ..
