Cracking of Concrete Cover in Frp Reinforced Concrete Elements under Thermal Loads

Synopsis: The effects of thermal loads on the structural performance of FRP reinforced concrete elements are analyzed in this paper. The difference in transverse coefficient of thermal expansion (CTE) between FRP and concrete causes the presence of tensile stresses within the concrete and, eventually, the formation of cracks when the temperature increases. As part of an inter-university experim...

Early-Age Cracking in Reconstructed Concrete Bridge Barrier Walls

An assessment of newly reconstructed reinforced concrete barrier walls on a highway bridge near Montreal indicated intense transverse cracking only a few days after concreting. Subsequent inspection of other concrete bridges in urban areas confirmed that such cracking is not uncommon. Analytical models, together with field and estimated data, were used to study the magnitude and roles of the fa...
