Stress Concentration Analysis in Concrete Round Dowels for Airport Jointed Rigid Pavement System
The objective of this paper is to analyze stress concentration in the concrete round the circumference of the dowels for airport jointed rigid pavement system. Based upon ABAQUS, a 3D finite element model for jointed rigid pavement is established by using 3D continuum finite element to model the dowels, and the actual interface conditions between dowels and concrete, and between slabs and base are considered. The status of stresses concentration including edge loading case and corner loading case are obtained through structural response analysis. The results indicate that the maximum principal stresses and shear stresses in concrete round the dowels are extremely high, and the magnitudes are about 10.0MPa and 5.4MPa for edge loading case and 16.5MP and 7.5MPa for corner loading case respectively. Further, primary cracks are prone to occur in the concrete round dowels, especially for edge load case, and localized crushed of concrete and looseness of dowels due to large stresses concentration may result in joint distresses.
