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 with the conventional cube CAU. The casting systems and clamps are described for manufacturing and handling the 15-t conventional cubic block and 16-t Cubipod prototypes used for the drop tests. Two separate reinforced concrete platforms were used for overturning and for free-fall tests, respectively. Compared with conventional cubes of similar size and concrete strength, Cubipods withstand drops that are more than 50% higher. Two extreme free-fall tests confirmed the structural robustness of Cubipod armor units. Manufacturing cycle time, as well as storage and handling procedures, are similar for both Cubipods and conventional cubic blocks. © 2011 American Society of Civil Engineers. Source
