Structural Behaviour of Ten Ton Dolos Armour Units

Abstract

This paper summarizes the results of a research program conducted to examine the structural behaviour of nine full scale ten ton Dolos armour units subjected to a well defined loading regime. Three unreinforced and six reinforced units were tested. The effects of three different types of reinforcement (rebars, hollow steel tubes, and prestressing bars) on the behaviour of the units was determined. Different design approaches for armour units are discussed and one possible new approach is presented.
