ABSTRACT

The first step in the process of repair and rehabilitation is the assessment of the structure to evaluate the following:

• causes of the corrosion of the steel; • the extent of the damage ; • the expected progress of the damage; • the influence of the damage on the structural safety of the structure,

and on its serviceability. On the basis of the initial assessment, the optimum strategy for repair

and rehabilitation should be chosen. The strategy adopted should also take into account economic aspects, which include not only the cost of the repairs, but also the overall state of the structure and the additional time period it is expected to serve. Details and guidelines for the choice of strategies are provided in a RILEM document [9.1].
