압축과 휨을 동시에 받는 케이블교량용 광폭 강박스거더의 강도상호작용

다국어 초록 (Multilingual Abstract)

This study investigates applicability of strength interaction equations in Eurocode 3 and AASHTO LRFD to wide steel box-girders in cable-supported bridges that are subjected to concurrent action of compression and flexure. Utilizing a finite element analysis package program, Abaqus, a partial segment of wide steel box girder separated from the completed actual cable-stayed bridges is modeled and ultimate strength analysis is conducted considering geometrical initial imperfections and residual stresses. After evaluating respective axial and flexural strengths, ultimate strength interaction behaviors are derived to confirm strength decrease effect due to combined actions. For the strength interaction between compression and flexure of wide steel box girders, Eurocode 3 is confirmed to provide safer evaluation of rather then AASHTO LRFD.
