Abstract

It is possible to apply the high-performance steels(HPS) to practical design not only light weight structures but also simple structures with simple weld details. However, from the results of previous researchers, it is found that the ductility of girder with HPS is reduced due to the increasing of yielding stress. Thus, the study on method to guarantee the proper ductility of girder with HPS is necessary. This paper investigates the flexural ductility of I-girders in negative moment region with HSB800(F y=680MPa). The flexural strengths of bridge girder which assumed to be made by using 800MPa class high performance steel are evaluated based on AASHTO LRFD design code. The results are compared with those from finite element analyses. Parametric studies are conducted in this study then the effects of yielding stress on ductility are finally discussed.
