Abstract

Reinforced concrete simply-supported grillage girder bridges are of multiple possible failure modes considering torsion and shear interactions. Equilibrium plasticity truss model was adopted to search for the first cross-section failure mode of the bridge structure. The component resistances were calculated according to Chinese JTG D62-2004 code, US ACI 318-11 code, and the equilibrium plastic truss model. The comparison shows that the consideration of torsion and shear will reduce the capacity of bridge components. Stirrup spacing was adjusted to control the failure mode to be bending dominated failure. Sensitivity analysis was performed and the results indicate that effective depth of girder is the most sensitive parameter to influence load carrying safety of the studied bridge considering the interaction of bending, torsion and shear.
