Description	Journal: Iop Conference Series: Earth and Environmental Science A practical combined algorithm for the corbel of common reinforced concrete bridge is put forward. Based on material nonlinearity, combining the professional finite element software Midas Civil and MIDAS FEA with Smeared crack model, the Thorenfeldt and Constant curves are used as concrete compression and tension constitutive model to numerical analyze the corbel's stress and crack. Example results show that the normal stress of the corbel and crack are greater than design value of C35 concrete tensile strength, and part areas are in the plastic state. The groove corner region of the corbel has abrupt stress. The crack of the corbel is firstly generated at the groove and the top plate, and gradually expands with the increase of the load coefficient. It develops sufficiently in the groove region, but there is not any full-length crack. The corbel has a group-strip-like crack farther from groove corner region. The calculation results are consistent with the bridge disease condition, which shows that Finite Element-Smeared Crack Combined Algorithm proposed in this paper is effective for the analysis of corbel.
