Introduction

The catastrophic earthquakes that struck several countries over the last 20 years brought to light the susceptibility of the existing building stock (Fig. 1). Old-type reinforced concrete (R/C) structures are characterized by insufficient reinforcement detailing (lack of stirrups for ensuring a certain ductility level, indirect supports, insufficient anchorages of bars), nonuniform distribution of stiffness and/or mass along the height of the building, insufficient foundation system, poor quality of materials, and various other weaknesses such as increased loading due to change of use and corrosion of reinforcement.
