As part of transportation systems, culverts are subjected to complex load conditions such as earth pressure and traffic live load. In addition, culverts may experience differential settlement of underlying soils, hydrostatic load, and aggradation/degradation scour. Combinations of these effects may cause crack formation or even structural failure. The objective of this paper is to study factors that lead to crack formation in the culvert-wing wall connection immediately after construction. Finite element models (FE) with Plaxis 3D software were used to analyze the stress distribution along the wing wall connection under different load scenarios and geometries. Mohr-Coulomb (MC) and Hardening soil (HS) non-linear material models were utilized. Tension stresses were occurred at the top of the wing wall as well as out of plane rotation away from the culvert, contributing to cracks as observed in the field.
