چکیده:

Lifelines are essential to urban life as they include all kinds of facilities and systems as water gas fuel , power communication and transportation . Seismic risk assessment of lifelines is considerably more complicated than that of a single structure on account of the geographical spread of lifelines. the scopr of this paper is to evaluate the influence of the uncertainties of seismic load and damage state definition in systems connectivity . a rapid pre-estimation of the reliability of the system just after the earthquake is conducted according to the consequences of the damages and final serviceability . it is summarized the framework of lifeline seismic analysis. in this case probabilistic seismic risk analysis by using mesh is done and then damage probability of pipelines derived . the final estimation of the seismic performance of the system is achieved by combining a probabilistic vulnerability curve and a monte carlo simulation for the definition of the damage state
