Study on Thermal Stresses the Extreme Temperature in Bridge Deck Pavements Using FEM Analysis

Article Preview

Abstract:

The thermal stresses at the extreme temperatures in bridge deck pavements (BDP) was analyzed in the paper. The sample bridge deck and asphalt concrete pavements were analyzed. The maximum principal and shear stresses in the BDP at the wide range of temperatures were calculated using 3D finite element method. The compared results showed a strong linear correlation between the BDP maximum principal stress and the elastic modulus. This linear relationship also existed between the shear stress and the elastic modulus. From the finite element analysis, it is found that the BDP elastic modulus affects the thermal stress more than the thickness of BDP. With the consideration of thermal stresses of BDP, the thickness of BDP from 6 to 12 cm is recommended for the BDP construction.
