Description:

Researchers have shown that the heat waves affect thermal expansion joints, accelerate material degradation, and increase stresses in prestressed concrete girders. In particular, experimental and analytical investigations indicate a significant increase in stresses at both the tension and compression regions during extreme summer temperatures. The increase of stresses may widen current cracks and create new cracks that accelerate concrete and steel deterioration. The effects of extreme temperatures may reduce the durability, serviceability, and stability of the bridge structures. The project investigated the effects of extreme temperatures on prestressed concrete bridges. The temperature profiles of two full-scale sections of a prestressed girder were monitored and compared to the profiles predicted using design standards. A finite element model was also developed to determine the temperature distribution within the cross-section.
