چکیده
In the present paper, Fragility Curves (FCs) of Reinforced Concrete (RC) building types with moment-resisting frame structure representative existing Italian stock have been derived through an analytical approach. The proposed methodology is based on Non-Linear Dynamic Analyses encompassing all steps required to bring about reliable as well realistic fragility results. First, prototype selected by considering main attributes affecting seismic vulnerability RC buildings, that is: age construction (i.e. ‘50 s, ‘70 s and ‘90 s), number storeys 2, 4 6 storeys), arrangement in elevation infills Bare-, Infilled-, Pilotis-frame) design level or gravity loads). A simulated has used for detailing at hand, whose non-linear dynamic response computed using a large set signals. signals purposely order approach elastic spectra provided code different return periods, being able take into account also record-to-record variability soil-amplification effects. specific relationship between considered engineering demand parameter inter-storey drift ratio) damage levels EMS-98 scale defined basis empirical data expert judgement.

Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...

Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...
