| Abstract: |
Application of twin I-girder bridge structure is very few in China. The structure is designed based on the requirement of bridge industrialization construction. So the structure has typically same spans, same cross section depth, and same cross section width with only two I girders and large deck width. Due to large deck width and weak torsional stiffness of I girders, the effect of distortion is more significant than traditional I girder system. The paper developed parametric study to investigate the distortion behaviour of twin I-girder bridge structure. The results show that it is not reasonable to use transverse distribution coefficient do design twin I-girder bridges. A modified coefficient is required. |
