A Study of Local Buckling of Steel Bridge Girders subtended to Possible Load Conditions during Construction by Incremental Launching Method

ILM 시공시 발생할 수 있는 하중조합에 대한 강교량 주형의 국부좌굴 연구

Recently, various and new special methods of construction about steel bridges have been tried, and the study about local buckling under this methods have been performed too. But because of various cases, structural analysis is performed to check safety for each step of construction, and this is not efficient and economical method for time and manpower. So, for solution of this problems, general method about checking safety needs to he developed. In this study, local buckiling of web of girder due to various load cases under construction by ILM(Incremental Launching Method) will be studio considering various parameters such as forces, aspect ratio, boundary condition and so on. Also interaction curve will he plotted for each case.
