This paper presents the finite element results of a parametric investigation of the U-shaped box culvert of prefabricated reinforced concrete subject to loading conditions. It was included outer size span length 4.80m, rise of 4.80m, laying width 1.5m and 0.4m slab and wall thickness. Its components consisted of two symmetrical u-shaped structures joined together using the tip at the end of the bell. It was not recommended for areas with excessive settlement where deep foundations were required. The upper and side ground pressure was considered in the culvert, which depends on the depth of the canal. The finite element method has been chosen for purpose of modeling and analyzing the structural behaver of the standard three dimensional solid and wire elements of the u-shaped box culvert under different loading conditions using ABAQUS-V6.14-4 due to its flexibility in creating geometry and material modeling. The culvert has been modeled using 3-D solid (C3D8R) elements reduce integration for concrete and 3-D wire (T3D2H) elements for reinforcement having geometric and material linearity as well as hybrid formulation. The reinforcement was modeled as rebar elements embedded in the surface element. Finally, the Finite element analysis (FEA) results were showed deflection and stress as well as effect of with and without distribution steel on the culvert.
