Abstract [sv]

I följande rapport redovisas så kallade designdiagram för dynamisk kontroll av järnvägsbroar. Syftet är att dessa ska kunna användas i tidiga skeden som en första bedömning om en given bro har möjlighet att klara kraven på komfort och trafiksäkerhet enligt SS-EN 1990, avsnitt A2.4.4.

Kraven baseras på vertikal acceleration och vertikal nedböjning av brodäcket samt vinkeländring vid upplag. Baserat på spännvidd och brons lägsta egenfrekvens kan erforderlig massa samt styvhet läsas av direkt i diagrammen.

Diagrammen gäller endast för broar med ballastfria spårsystem och största hastighet sth = 320 km/h. Diagrammen är framtagna baserat på en 2D balkmodell med konstant massa och styvhet samt fasta upplag och är giltiga endast under dessa förutsättningar.

Abstract [en]

In this report, so called design charts for dynamic assessment of railway bridges are presented. The aim is to use these diagrams in early stage design of bridges, to determine if they are likely to comply with the requirements for riding comfort and traffic safety stated in SS-EN 1990, section A2.4.4.

The requirements are based on vertical acceleration and vertical displacement of the bridge deck, as well as end rotation at supports. Based on the span length and the fundamental natural frequency, the required mass and stiffness can be obtained directly from the diagrams.

The diagrams are only valid for bridges with ballastless track systems and an allowable speed sth = 320 km/h. The diagrams are developed based on a 2D beam model with constant mass and stiffness and fixed supports. The diagrams are only valid under these assumptions.
