Load Distribution Factors in Simply Supported Skew Bridges
Simply supported bridges consisting of five I-section concrete girders are analyzed using the finite-element method. The main parameters of this study are: girder spacing (1.8-2.7 m), span length (25-35 m), skew angle (0-60°), and different arrangements of internal transverse diaphragms. Results of...

Zusammenfassung: | Simply supported bridges consisting of five I-section concrete girders are analyzed using the finite-element method. The main parameters of this study are: girder spacing (1.8-2.7 m), span length (25-35 m), skew angle (0-60°), and different arrangements of internal transverse diaphragms. Results of reliable analysis based on the finite-element method show that, in right bridges, American Association of State Highway and Transportation Officials distribution factors are conservative and in skew bridges, these factors are very conservative. |
