“…The results show that the concrete strength, anchorage length, stirrup ratio and cover thickness have a positive effect on bond strength, while only the diameter of rebar has a negative effect. This conclusion has also been verified in previous studies (Léon et al, 2019; Zhe et al, 2021; Gao et al, 2019). In addition, the quantitative effect of changes in parameters on bond strength is further described as follows.…”

In this paper, the influence of concrete strength, diameter, cover thickness, anchorage length, and stirrups ratio on the bonding performance of the HSCR rebar in concrete are experimentally investigated. A nonlinear FE model for simulating the bond performance between HSCR and concrete is established and validated, and the influencing parameters are parametrically investigated. Moreover, the applicability of the ultimate bond strength model for HSCR-concrete is comparatively discussed, and a new model is proposed and validated to give relatively accurate prediction. Based on the proposed model, the anchorage reliability analysis is conducted, the influencing parameters as well as their variation on the reliability of bond strength are discussed, and the reliable anchorage length is recommended.

“…By analyzing the propagation characteristics of guided waves, including wave speed, attenuation, and mode conversion, engineers can identify and localize various types of structural anomalies, such as cracks, voids, and debonding. Guided wave-based SHM systems offer the advantage of long-range inspection capability, allowing for the assessment large concrete structures with minimal surface access [3,4].…”

“…The information gathered by sensors and other monitoring devices is crucial in evaluating significant structural performance parameters, like stability, structural integrity, and load-carrying capacity. Subsequently, these parameters are utilized to conclude the concrete effects of infrastructure on health conditions and performance [3]. Engineers can use this information to identify potential issues and decide when and how to restore or strengthen the structure.…”

“…The sensors are embedded directly into concrete structures to monitor moisture content, temperature, and chloride ion concentration parameters. Previous reviews have highlighted the potential of these sensors but often lacked in-depth analysis of their longterm durability, accuracy, and scalability for large-scale implementation [3,5,[11][12][13].…”

Structural health monitoring (SHM) is crucial for maintaining concrete infrastructure. The data collected by these sensors are processed and analyzed using various analysis tools under different loadings and exposure to external conditions. Sensor-based investigation on concrete has been carried out for technologies used for designing structural health monitoring sensors. A Sensor-Infused Structural Analysis such as interfacial bond-slip model, corroded steel bar, fiber-optic sensors, carbon black and polypropylene fiber, concrete cracks, concrete carbonation, strain transfer model, and vibrational-based monitor. The compressive strength (CS) and split tensile strength (STS) values of the analyzed material fall within a range from 26 to 36 MPa and from 2 to 3 MPa, respectively. The material being studied has a range of flexural strength (FS) and density values that fall between 4.5 and 7 MPa and between 2250 and 2550 kg/m3. The average squared difference between the predicted and actual compressive strength values was found to be 4.405. With cement ratios of 0.3, 0.4, and 0.5, the shear strength value ranged from 4.4 to 5.6 MPa. The maximum shear strength was observed for a water–cement ratio of 0.4, with 5.5 MPa, followed by a water–cement ratio of 0.3, with 5 MPa. Optimizing the water–cement ratio achieves robust concrete (at 0.50), while a lower ratio may hinder strength (at 0.30). PZT sensors and stress-wave measurements aid in the precise structural monitoring, enhanced by steel fibers and carbon black, for improved sensitivity and mechanical properties. These findings incorporate a wide range of applications, including crack detection; strain and deformation analysis; and monitoring of temperature, moisture, and corrosion. This review pioneers sensor technology for concrete monitoring (Goal 9), urban safety (Goal 11), climate resilience (Goal 13), coastal preservation (Goal 14), and habitat protection (Goal 15) of the United Nations’ Sustainable Development Goals.

“…To better describe bond behavior, many researchers have attempted to build mathematical models that take into consideration the effect of stirrup confinement, concrete strength, etc. (Eligehausen et al 1983;Shima et al 1987;Bigaj 1995;Gedik et al 2011;Chiriatti et al 2019). Specifically, Eligehausen et al (1983) proposed a bond stress-slip relationship for confined concrete under monotonic and cyclic loading.…”

Change in the mechanism of post corrosion bond behavior was investigated in a previous experimental study by analyzing the deformations in concrete using digital image correlation (DIC). Using their DIC data, this study focuses on the local strain non-uniformity in reinforcing bar during the uniaxial tensile test due to the effect of rib height reduction and corrosion layer. The results show that, the local strain below the rib tip is higher than that below the flat part between ribs, due to compressive stress resulting from mechanical interaction at the rib tip. Furthermore, the non-uniformity in local strain is less pronounced in highly corroded reinforcing bar because less compressive stress is transferred due to gentler rib slope. In highly corroded reinforcing bar, the appearance of non-uniformity in local strain is delayed since the accumulated corrosion product on the reinforcing bar surface delays the mechanical interaction and stress transfer between the concrete and the reinforcing bar.
