Paying attention to the noise generated from steel and concrete composite bridges is an essential environmental preservation measure in todays transport networks.For the composite girders used in comparatively large quantities on railway bridges in urban areas in particular,noise prevention measures are normally taken for web plates and bottom flanges where steel is exposed.

Bridge is modem communications key point,however,its bearing capacity would reduce under action of environment and vehicle in the long-term operation.In recent years,bridge health monitoring and maint
U rib is the main force structure of deck system.But it is also one of the positions where fatigue damage occurred easily.According to the results of the fatigue crack statistics by the Japan steel st
A new evaluation method for the safety of cable bands on the suspension bridges of the Honshu-Shikoku Bridges at the maintenance stage has been established.A cable band is a member to connect a main c
A new type of pot beating was proposed and used to replace old railway bridge beatings.Different from ordinary pot bearings,main components are set in reverse order so that dust will not reach inside
Based on the finite element model,the local fatigue stress is analyzed at the position of U rib to deck weld connections.Different construction details are considered,including the thickness of the de
There are improvement methods of fatigue strength,such as finishing methods and peening methods.Finishing methods aim to decrease stress concentration at weld toe.Peening methods aim to decrease high
