Abstract: The ability to properly assess existing reinforced concrete (RC) structures provides an opportunity to prevent costly rehabilitations or replacements and aid in the optimization of future designs. Distributed fiber-optic ...

Abstract: Train derailments caused by buckled or broken rail continue to be both a safety and economic concern for North America’s railway industry. These track failures are often attributed to excessive axial stresses in continuous ...

Abstract: A retrofitting technique that uses prestressed unbonded carbon-fiber-reinforced polymer (CFRP) straps to provide additional shear capacity has previously been shown to be successful under short-term static loading conditions. ...

Abstract: A prestressed carbon fiber-reinforced polymer (CFRP) strap retrofitting system has been found to significantly enhance the shear capacity of existing reinforced concrete beams. In previous studies, the CFRP straps were ...

Abstract: A retrofitting technique has been developed that uses carbon fiber-reinforced polymer (CFRP) straps to increase the shear capacity of reinforced concrete beams. The vertical straps are not bonded to the beam but are instead ...

Abstract: Two corrugated steel pipes were repaired with grouted high-density polyethylene (HDPE) slipliners, one with low-density (i.e., low-modulus and low-strength) grout, and the other with high-density (i.e., high-modulus ...

Abstract: Typical design and installation methods for corrugated steel culverts involve consideration of a minimum burial depth and most current North American design codes consider failure only due to excessive circumferential force ...

Abstract: Quantitative measurements are necessary to support accurate assessments of culverts; however, the choice of which sensor to employ to support these assessments is often not clear. An in-service corrugated steel culvert ...

Abstract: North America’s growing demand for rail transportation capacity, in terms of both train weight and length, has raised concerns regarding the performance of older bridges and has presented the need for improved assessment ...

Abstract: The performance of large diameter corrugated steel culverts/pipes under varying cover depth up to deep burial has previously not been investigated in a laboratory setting due to limitations associated with the application ...
