Building structures have been designed for more than 40 years to protect life in the event of a major seismic event. In order to achieve this goal with a minimal initial investment, structures are designed, using the ductility principle, as sacrificial systems, undergoing significant plastic deformations in the main structural elements, which progressively deteriorate. If in the design codes the structural damage is to some extent explicitly accepted and quantifiable, problems related to non-structural damage are addressed much more vaguely. This no longer meets market and society requirements. New structural systems are needed, which are not only efficient in reducing structural and non-structural damage, but also offer good re-centring capability, durability, reparability and affordability, accompanied by accessible design methods. This paper reviews the principal solutions that can be used to achieve these goals. Their advantages and limitations are analysed, as well as their potential as damage tolerant structural systems.
