<p>Dynamic analysis is commonly conducted to design bridges for high speed railway lines. Classically, two aspects are analyzed at design stage: the vertical acceleration and vertical deflection of the deck which are limited in order to prevent the track instability and the passenger comfort. These aspects were analyzed by Systra for the major international projects: Taipei – Kaohsiung line in Taiwan, “Channel Tunnel Rail Link” in the UK (CTRL), “Contournement Nîmes Montpellier” in France (CNM line), Tanger – Kenitra line in Morocco, Tianxingzhou Yangtze River Bridge in China and Dodam - Yeongcheon line in Korea.</p><p>More recently, some high-speed railway line projects have been designed to match a 400 km/h operation speed, such as Moscow-Saint Petersburg line project in Russia, and the European Research Project “Capacity for Rail”.</p>
