Numerical analysis of Fracture behavior of CFRP Sheet–Strengthened notched Concrete Beams [PDF]
The serviceability and safety of building and bridge structures may gradually degrade due to long term use, natural environmental deterioration, poor initial design and/or construction, increased design loads, extreme events such as earthquakes, and/or ...

Load-cmod data analysis for crack closure [PDF]
The use of load/crack-mouth-opening displacement (CMOD) records during fatigue cycling to estimate crack closure is evaluated by comparing load/CMOD values to benchmark crack opening data. Numerical differences between crack-opening stress values estimated by load/CMOD and the benchmark crack openings suggests that CMOD-estimated closure cannot ...
