ABSTRACT
ABSTRACT: Some long viaducts have been constructed in Ciudad de Mexico in the recent past. As it is very well known Mexico City is quite vulnerable to earthquakes. Concerning the consequences of seismic events on this kind of structures is largely unknown. So, a fast and precise assessment would be extremely useful for continuing the operation of the infrastructure without compromising safety. This paper is proposing a methodology for tackling these problems, based on the combined use of Finite Element Modeling and Structural Health Monitoring practices. This methodology involves the implementation of precise FEM models combined with real-time, web-based remote monitoring systems providing dynamic data obtained from a sensor networks what can provide a deep and fast knowledge of the structures’ and of the dynamic behavior and post-earthquake state. The results obtained from the monitoring implemented on 2014 and the comparison with the results of the FEM dynamic analysis performed are presented. A method for evaluating the real behavior of a long viaduct under the effects of a seismic load is presented.
