On the Assessment of the seismic performance of Reinforced Concrete existing Buildings

Lots of reinforced concrete constructions built in Italy up to 1980s have been designed in absence of seismic codes. Therefore, the assessment of their behaviour under earthquake motion and the following seismic vulnerability evaluation is a very key topic. In the present paper, various building designed without considering the seismic action have been analysed pointing out the main parameters influencing their behaviour under earthquake motion and their seismic vulnerability
