DESCRIPTION:The increasing demand for mobility worldwide has led to an eve
 r-increasing expansion of railway networks. Such a rapid expansion poses a
  challenge to guaranteeing quality\, reliability\, efficiency\, and\, most
  importantly\, the safety of railway infrastructure. A large portion of ra
 ilways spans across bridges\, which must also accommodate the rising deman
 ds for mobility and increased travel speeds\, placing additional demands i
 n terms of imposed loads. At the same time\, bridges worldwide suffer from
  aging\, leading to the deterioration of their structural integrity. Such 
 needs call for special attention during the design phase and later during 
 operation. The latter constitutes the operation condition monitoring of br
 idges and aims at ensuring their safe operation during their lifetime. To 
 this end\, this talk presents\, first\, recent advancements in the field o
 f vehicle-bridge interaction on railways\, which could lead to safer pract
 ices in railway bridge design. This part lies upon a detailed forward mode
 ling of vehicle-bridge interaction and the development of consistent decou
 pling methodologies. The second part of this talk examines the inverse veh
 icle-bridge interaction as a principle to develop efficient in-direct moni
 toring methodologies to assess the structural health of railway bridges.
