Анотация
"The present paper deals with the problem of computing analytically fragility curves of bridges. The methodology presented involves the use of the Finite Element Method (FEM) and of the non-linear static pushover analysis for the computation of the capacity curve of the bridges in combination with inelastic demand spectra for the estimation of the degree of damage for a given peak ground acceleration (PGA). Emphasis is given here for applying the developed methodology to some special bridges of the motorway Egnatia Odos, in Northern Greece. The vulnerability analysis of these bridges represents a critically important step in their seismic damage estimation process. The relevant fragility curves provide the probability that a specific damage level will be exceeded for a given intensity of a seismic event."
