Condition assessment of torpedo launch pad station structure in Rijeka

The world’s first torpedo has been manufactured in Croatia, in the city of Rijeka in 1866, where the production of torpedoes continued until 1966. Before shipment, each torpedo had to pass very complex testing, including the test-launch in order to confirm the regularity of its direction. The current reinforced-concrete launch pad station was built between 1928 and 1942 in three phases and therefore has highly heterogeneous properties regarding the shape of the structure and quality of the materials. In order to perform condition assessment of the launch pad structure detailed structural investigation has been performed on a large number of test locations and samples, where mechanical and durability properties of concrete have been tested and chloride content measured. A 3D laser scanning survey has also been conducted in order to obtain the cross-section dimensions and the overall form of the structure. Based on the gathered data a structural reanalysis of the bearing capacity of the current launch pad structure has been made. The heterogeneous material properties have been analysed together with their influence on the bearing resistance of the current structure.
