| Abstract: |
A comparative study of the design example of highway steel girder bridges is performed for the same design requirements using the design codes, AASHTO-LRFD of USA and Japanese Specifications. As a result, AASHTO-LRFD-based girder height is significantly smaller than the Japanese one, which results in difference in stiffness of the girders. Also, differences exist in other design provisions such as impact factors, spacing of cross frames, limitation of deflection, etc. A study for the benchmark design is also proposed to investigate the rationality of bridge design further. |
