Title: CURVES OF BRITTLENESS FOR THREE TYPICAL CONCRETE ROAD BRIDGES.
Author(s): Consuelo Gómez Soberón e Iván Soria Rodríguez
Appears on pages(s): 26-42
Keywords: fragility curves, seismic analysis, bridge analysis, damage assessment, probabilistic analysis.
Abstract:"This work presents fragility curves for the seismic loading of three concrete bridges, in typical Mexican roads. These structures were modeled elastically to verify and calibrate their dynamic characteristics as non-linear systems, for the damage caused by seismic loading. To define the seismic hazard in bridges, accelerograms were selected at stations near your location, and then simulated as artificial logs, similar to spectrum pseudovelocity. Fragility curves were defined by simulation, so that the random nature of the problem was considered, assuming as random variables the mechanical properties of the material and seismic load.
By nonlinear analysis –damage is obtained, which defines the curves. The comparison between the curves of the elements of each bridge –indicates those elements susceptible to seismic loading, while comparing the fragility curves of the bridges shows the system with a greater possibility of damage."
