A Finite Element Analysis of Coner Cracks in Cement Concrete Pavements

시멘트 콘크리트 포장도로의 우각부균열에 대한 유한요소해석

Most defects in the cement concrete pavement take place mainly on the joints. These corner cracks don't happen as often as others relatively. it happens continuously. In order to analyze the structural behavior of the corner cracks, The finite element structural analysis was performed on the representative section of the cement concrete pavements using JSLAB which uses FEM analysis method. On plain cement concrete pavements, The result shows that loading not only on the joints but also on the center of slab brings out the maximum stress on the corner of slab and it is expected to make the corner cracks.
