Abstract

This paper intends to review the experimental research work performed at the University of Hannover on the structural stability of tetrapods. It presents particularly the first results from the hydraulic and pendulum tests which suggest that: the most critical location of the armour units with respect to structural stability has been found at and slightly above still water level; for regular waves a well defined relationship can be found between incident wave parameters and the induced dynamic and guasi-static stresses. In the case of irregular waves, however a clear relationship appears to exist only for guasi-static loads; the critical IRIBARREN-Parameter with respect to structural stability is in the same range as the one found for hydraulic stability; a linear relationship has been found between impact bending stress and impact velocity for the tested tetrapods 50 kg - 1.8 t.
