“…The direct relationship between curing time and bond strength emphasizes the significance of considering concrete age in assessing CFRP bond performance. Unique failure modes associated with different curing times and bond materials provide crucial insights for predicting and enhancing the reliability of CFRP-strengthened structures [2,11]. Practical implications of the study extend to material selection, construction scheduling, and failure mode considerations during design.…”

“…The compressive strength of these resins exhibited distinctive patterns, with UHPC rapidly reaching 95.3 MPa at 3 days. Furthermore, the study identified variations in failure modes over time, specifically noting a shift in the plane of failure for mortar-bonded interfaces [5,6]. This evolving body of research challenges conventional norms and underscores the nuanced interplay between inorganic resins, curing periods, and NSM CFRP interfaces.…”

This study explores the application of various inorganic resins in the Near-Surface Mounted (NSM) strengthening technique, aiming to provide alternatives to traditional organic resins. The research centers on sixty single lap-shear concrete blocks, employing four distinct adhesives—ordinary mortar, Ultra-High-Performance Concrete (UHPC), geopolymer, and polyester-silica—for bonding Carbon Fiber-Reinforced Polymer (CFRP) strips to the concrete blocks. Conducted under monotonic loading, the investigation assesses the bond characteristics between the inorganic resins and both CFRP composites and the concrete substrate. Interfacial behaviour, bond strength, and failure modes are meticulously analyzed, shedding light on the performance of each adhesive. The study reveals insights into the efficiency of the NSM system, emphasizing the significance of the bond between FRP composites and concrete for optimal strengthening. The findings underscore the limited research on NSM systems using inorganic resins, providing a foundation for further exploration in this domain.

“…The setup for compressional tests includes hydraulic jacks against a weighted platform, with a detailed description of the calibration and arrangement necessary for accurate measurement of pile head movements. The primary objective in compression tests is obtaining a load-movement curve [12,13]. The methodology outlines equations for computing the elastic deformation of a pile, considering factors like test load, pile length, cross-sectional area, and the elastic modulus of the pile material.…”

“…The methodology details the types of strain gauges used for steel and concrete piles and the importance of ensuring these gauges remain dry to avoid failure due to corrosion [16,17]. A comprehensive analysis of the results would include a detailed comparison of the bearing capacities calculated by the β-method and FEM, discussing the significance of the findings in the context of soil properties and pile design [18,19].…”

This paper presents a comprehensive study on evaluating the load capacity of 14H-piles in cohesionless soils for Edward's infrastructure project[1]. The project, overseen by the Federal Highway Administration (FHWA) and the Colorado Department of Transportation (CDOT), focuses on bridge replacements in Edwards, Colorado, with an emphasis on foundation improvements using driven pile foundations[2]. The research utilizes Finite Element Analysis (FEA) and the β-method to assess the total bearing capacity of 14H-piles in sandy soil conditions[3]. Field exploration, including Standard Penetration Tests (SPT), is conducted to determine soil parameters, followed by calibration of soil strength parameters. The study involves modelling the piles using the Soil-Structure Interaction 3-D program (SSI3D) and comparing the total bearing capacity obtained from FEA with nominal capacities calculated by the β-method. Additionally, the paper discusses load resistance and factor design, as well as the importance of static load testing for validation[4]. The results highlight the efficacy of FEA in predicting pile behaviour and provide valuable insights for foundation design in similar geological settings.
