Article Abstract
Reinforcement corrosion poses a great threat to the safety of reinforced concrete structures, and the fiber-reinforced polymer is the ideal material to partially replace steel bars due to the high strength, light weight and good durability. However, the selection of appropriate fiber materials and a reasonable ratio of fiber bar to steel bar is not clear. Here, we measured the mechanical properties of fiber bars containing aramid fiber and carbon fiber. The deflection deformation, crack distribution and maximum crack width of the concrete upon various loads were experimentally and theoretically investigated. The predictions of the maximum crack width and deflection of reinforced concrete beams under various loads were proposed in ACI standard, which may provide guidance for further applications of fiber-belt-bar-containing concrete beams.

Hollow ultra-high-performance concrete (UHPC) members subjected to axial pre-compression and torsion represent realistic loading scenarios commonly observed in modern engineering structures, including bridge box girders, prestressed members, and high-rise tubular columns. The inclusion of web openings further reflects practical design requirements. However, the combined effect of pre-compression, torsion, and openings on UHPC members remains insufficiently addressed in literature.

Fire analysis of reinforced concrete (RC) structures is vital for understanding their behavior under extreme conditions. In real-world scenarios, uncontrolled fires can damage buildings and infrastructure substantially, undermining their structural integrity. Assessing the performance of RC beams under fire exposure is crucial for ensuring the safety and reliability of structures.

GFRP bars can be used partially or fully instead of steel bars in RC-beams to eliminate corrosion problems, especially in harsh environments. Also, the implementation of the combined use of engineered cementitious composite (ECC) and the hybrid (steel-GFRP) reinforcement in concrete beams can enhance strength and serviceability. In this paper, seven beams; one as a control beam cast with traditional concrete, and six partial ECC RC-beams with GFRP bars only or RC-hybrid (steel-GFRP) bars were designed to investigate both deflection and ductility behaviour of such beam type.

The construction industry is exploring alternatives to traditional steel reinforcement in concrete due to steel's corrosion vulnerability. Glass Fiber Reinforced Polymer (GFRP) and Basalt Fiber Reinforced Polymer (BFRP), known for their high tensile strength and corrosion resistance, are viable options. This study evaluates the flexural performance of concrete beams reinforced with GFRP, BFRP, and hybrid systems combining these materials with steel, following ACI 440.

Visual inspection of civil infrastructure for structural health assessment, as performed by structural engineers, is expensive and time-consuming. Therefore, automating this process is highly attractive, which has received significant attention in recent years. With the increasing capabilities of computers, deep neural networks have become a standard tool and can be used for structural health inspections.
