Characteristics of the stress on CWR for railway bridge design

Characteristics of the stress on Continuous Welded Rail(CWR) were investigated to apply to design procedure for railway bridge design. Actions due to change in temperature, braking/traction and bending of the deck were considered in this interaction analysis between CWR and bridge deck. The bridge parameters such as static arrangement of the deck and support stiffness were taken into consideration to examine the influence of the parameters on the additional rail stress. The final results of this study, which include the displacement as well as the stress will be presented in the form of the design chart in future.
