Abstract

Abstract: Rigid pavements are complex structural systems that are composed of numerous discrete concrete slabs, longitudinal and transverse joints are provided between the slabs, which may or may not include dowel bars. Dowel bars connect concrete slabs and transfer wheel load across the joint primarily through shear force. Many response models based on the finite element method have been developed for the analysis of jointed pavement slabs. Despite the notable improvement, important considerations were overlooked. Such approximation may affect the results obtained at the joint and cause it to be unrealistic. In the current research,the development of finite element modelwas conducted using the finite element code ABAQUS(6.13). The required modeling techniques for developing this model are illustrated , this include the meshing techniques, boundary condition, analysis process and required techniques for each case was included. Verification process was presented to ensure model reliability. The final step involves solving themodel, calculating the stresses, and analysis of the results.
