Ballasted track interaction effects in railway bridges with simply-supported spans composed by adjacent twin single-track decks
(Elsevier, 2021-09-08)
This paper is devoted to track-bridge interaction phenomena in railway bridges of short simply-supported (SS) spans composed by ballasted tracks. These structures may experience high vertical acceleration levels under ...

Influencia de los anclajes en vigas de hormigón armado reforzadas con laminado de fibras de carbono
(Asociación española de ingeniería mecánica, 2004)
La resistencia a flexión de vigas de hormigón armado puede ser incrementada adhiriendo externamente láminas de fibras de carbono (CFRP) en la zona traccionada. En muchos casos, no se alcanza la resistencia última del ...
