“…Tedesco et al (1987Tedesco et al ( , 1991Tedesco et al ( , 1992, Scott et al (1990), and Tedesco (1992, 1993) have all applied FEM based numerical programs to simulate the structural response of the Dolos unit under static and dynamic loading conditions. They plotted time histories of stresses at several key points on Dolosse units and derived iso-stress curves for Dolosse units of different sizes.…”

Rubble-mound breakwaters covered by armour layers of concrete units are widely used coastal structures. In this work, a three-dimensional fracture model in the context of the combined finite-discrete element method is applied to investigate the structural integrity of two types of concrete armour units under dynamic and extreme loading conditions. Dolosse units are simulated in drop tests and pendulum tests, and Core-Loc units of prototype scale are simulated under an imaginary extreme loading condition. The whole structural response of concrete armour units is accurately captured and the results provide a better understanding of damage and reserve stability of such systems.

“…Proper attention to scaling is required in order for the results of the small-scale structural measurements to be meaningful. Scott, Turcke, and Baird (1990) and more recently, Anglin et al . (1990) have reported the results of a large series of parametric physical model tests using small-scale model dolosse.…”

Prescribed by ANSI Std Z39-18 298-102 13. ABSTRACT (Concluded) can add significantly to the unit's strength, while sacrificing little hydrodynamic stability, and that large dolosse over 30 tons require some strengthening scheme. The methods discussed in this paper provide a complete procedure for determining a design stress within a hydrodynamically stable dolos and can be used as an outline in the design of other slender armor unit shapes.

Abstract:In this paper, an experimental methodology is described to assess the structural strength of unreinforced concrete armor units (CAUs). The methodology is applied to measure the structural integrity under impact loads of the new Cubipod CAU compared to the conventional cube CAU. The casting systems and clamps are described to manufacture and handle the 15-tonne conventional cubic block and 16-tonne Cubipod prototypes used for the drop tests. Two separate reinforced-concrete platforms were used for overturning and free fall tests, respectively; Cubipods withstand drops more than 50% higher than conventional cubes of similar size and concrete strength. Two extreme free fall tests, confirmed the structural robustness of Cubipod armor units. Manufacturing cycletime as well as storage and handling procedures are similar for both Cubipods and conventional cubic blocks.
