A Study on Verification Test of T-MAT Type Expansion Joint for Railway Bridge

Expansion joint is the absorbing structure when the upper structure of bridge have the drying shrinkage and creep from the change of temperature or construction badness. Because it has the fatigue from continuous vehicles traffic. the durability and performance is verified by the static and dynamic loading test In this study. we make the decision that T-MAT type expansion joint is applied in railway bridge and the expansion joint was tested by the criterion of Korea High Speed Rail Construction Authority.
