Loads to be considered in railway bridge design
Format: Downloadable
IRS 70776-1 describes the loads to be taken into account in the design of railway bridges.
This IRS defines imposed loads (load models and characteristic values) associated with rail traffic which include:
- vertical loads for bridges,
- vertical loading for earthworks,
- dynamic effects,
- centrifugal actions,
- nosing action,
- braking and acceleration actions,
- and actions for Accidental Design Situations corresponding to the derailment of rail traffic on the bridge.
It gives also rules and methods for establishing combinations of actions and design values of actions to be taken into account in limit state design.
The commissioning party should specify additional requirements for the design of roofed bridges, moveable bridges or bridges carrying road and rail traffic or other structured carrying rail traffic loads (e.g. backfill behind a retaining wall).
In countries where national regulations are in place, such rules should be considered in conjunction with or in place of this IRS. For EU member states, Eurocodes and other EN standards should be applied in accordance with the applicable regulatory framework.
