Evaluation of Reinforced Concrete T-Beams Retrofitted in Shear with Mechanically Anchored Dry Carbon Fiber Sheets

Fractal characteristics and damage evaluation of corroded beams under four-point bending tests based on acoustic emission techniques

“…Further, r 1 = 0.5σ, r 2 = 1.0σ, r 3 = 1.5σ, r 4 = 2.0σ, are chosen to represent the variation of r. And the averages of the quantities are defined as Eq (15):…”

“…Acoustic emission (AE) technique is a non-destructive testing technique, which provides an objective assessment of various damages to RC structures, such as cracks, honeycomb, and corrosion [8][9][10][11][12]. It uses AE sensors to passively capture elastic wave signals generated by material damage or deformed [9,[13][14][15]. AE technique has the advantages of high sensitivity [16] and the ability to detect damage in real-time [17], making it an effective tool for monitoring the evolution damage of RC structures.…”
