In recent years,prestressed concrete continuous rigid frame bridge has been widely applied in the field of road traffic in china.However,this type of the bridge is often accompanied by long-term deflection,box girder cracking and other diseases; the durability and bearing security during bridge life cycle are concerned.

There is a need to extend the life of many existing railway bridges.To facilitate this is one of the objects of the EC-FP7-Project MAINLINE,covering a period from 2011 to 2014,http//mainline-project.e
The steel truss railway bridge at (A)by River in Sweden was built in 1957 with a span of 32m (105 feet).In 2012 it was replaced by a new steel beam bridge and the old bridge was placed beside the rive
Atmospheric corrosion is a commonly observed cause of deterioration in metallic structures,such as steel railway bridges.The progression of corrosion damage can lead to inadequate performance and redu
Structural monitoring systems are important in civil engineering.However,traditional structural monitoring systems have disadvantages such as the shorter life span of sensors relative to that of the s
This paper presents a seismic repairing of reinforcement concrete bridge column using steel jacketing.An OpenSees-based simulation model of bridge column,considering inelastic flexure,bond slip,and bu
For existing reinforced concrete (RC) bridges,the structural performance deteriorates due to corrosion of reinforcing steel,particularly in a polluted environment.The deterioration continues and becom
Rebar corrosion is one of the primary cause of structure deterioration and durability failure for existing reinforced concrete (RC) bridges.The most concern related to rebar corrosion is the associate
In Taiwan,many steel and RC structures near the coast have chloride-induced damage.As the service period of structures increases,their safety and serviceability decrease.Restated,the original designed
The identification and quantification of social costs in bridge maintenance have been studied over past two decades.There is a need to involve these social costs in the life cycle optimization of brid
Deep beams are loaded as beams but have a small shear span/depth ratio.They can be used in many structures,such as bridges,tall buildings,foundations,and offshore structures.The conventional beam theo
