Journal ArticleDOI
Concrete structural health monitoring using embedded piezoceramic transducers
TL;DR: In this article, the authors used piezoceramic transducers for damage detection of a 61 m long reinforced concrete bridge bent-cap in order to identify the existence and severity of cracks inside the concrete structure.
Journal ArticleDOI
Smart aggregates: multi-functional sensors for concrete structures—a tutorial and a review
TL;DR: In this paper, the authors proposed a multi-functional smart aggregate for early-age concrete strength monitoring, impact detection and structural health monitoring, which can be applied to the comprehensive monitoring of concrete structures from their earliest stages and throughout their lifetime.
Journal ArticleDOI
Concrete early-age strength monitoring using embedded piezoelectric transducers
TL;DR: In this article, a fuzzy logic system is trained to correlate the harmonic response amplitude with the concrete strength based on the experimental data, and the experimental results show that the concrete strengths estimated by the trained fuzzy correlation system matches the experimental strength data.
Journal ArticleDOI
Active interface debonding detection of a concrete-filled steel tube with piezoelectric technologies using wavelet packet analysis
TL;DR: In this article, an active interface condition monitoring approach for concrete-filled steel tube (CFST) by the use of lead zirconate titanate (PZT) piezoceramics based functional smart aggregates (SAs) embedded in concrete as actuator and PZT patches bonded on the surface of the steel tube as sensors is proposed and verified experimentally.
Journal ArticleDOI
Health monitoring and rehabilitation of a concrete structure using intelligent materials
TL;DR: In this article, the authors presented the concept of intelligent reinforced concrete structure (IRCS) and its application in structural health monitoring and rehabilitation, which has multiple functions including self-rehabilitation, self-vibration damping, and self-structural health monitoring.
