The experience gained from field observations and backanalysis led to improvement of the level of knowledge and the evolution of seismic codes. The interest of the research munity is focused on buildings that do not ply with current seismic codes and exhibit deficiencies such as poor detailing, discontinuous load paths and lack of capacity design provisions. Since such buildings prise the majority of existing building stock, retrofitting is a rather critical issue. Rehabilitation schemes that will provide costeffective and structurally effective solutions are necessary. Many intervention methods used in the past have been revised and developed in the light of the new seismic code requirements and new methods often based on new materials (. fiberreinforced polymers FRPs) have been proposed. In this paper, the term ‘rehabilitation’ is used as a prehensive term to include all types of repair, retrofitting and strengthening that lead to reduced earthquake vulnerability. The term ‘repair’ is defined as reinstatement of the original characteristics of a damaged section or element and is confined to dealing with the asbuilt system. The term ‘strengthening’ is defined as intervention that lead to enhancement of one or more seismic response parameters (stiffness, strength, ductility, etc.), depending on the desired performance. Framework of seismic rehabilitation Performance objectives are set depending on the structural type, the import
