JES 공법의 JOINT ELEMENT 이음부에 관한 연구

초록

Recently developed JES(Joint Element Structure) Method was researched as a more safe and economic method than other under pass construction method and was applied to many construction sites. The joint element connection of JES Method is the most important factor for the to behavior of structure. The connection of JES method is filled with the mortar, and the steel and mortar of connections produce the same behavior as one material. The results of experience and numerical analysis are following; The maximum internal stress of connection is decided by the end of connection. also, The connection of joint element structure method have sufficient internal stress against fatigue.
