It is most important that developments in new design concepts are assimilated in assessment and strengthening philosophy in order to avoid a conceptual gap between existing and new construction. Therefore, structural intervention methods must comply with capacity-design requirements, used in design of new structures, for tighter control over individual design response parameters, such as stiffness, strength and ductility. These play a vital role in the global response and failure mode of RC structures, and thus need to be individually assessed and modified in order to optimise the response of the upgraded structure. Selective repair and strengthening techniques, capable of individually affecting such design parameters, have been developed and recently tested under dynamic conditions. In this paper, a detailed description of these experiments is presented and the most relevant results and observations are discussed. These not only confirm the effectiveness of the proposed selective schemes and their feasibility for practical applications, but also further validate previously derived formulae that can be employed in design.
