“…A series of pull-out tests were conducted in order to discover the interface properties between CFRP bar and concrete substrate. Considering that the adhesive layer thickness soundly influences the efficiency of the reinforcement system [ 26 ], different specimens were prepared with the adhesive thickness ranging from 0.1 to 2.0 mm. The details of specimens and experimental results are shown in Figure 3 .…”

Deep T-section beams have been widely used in engineering structures due to their high bearing capacity, high construction efficiency and economic benefits, while the current beam design theory can hardly interpret reasonably the mechanical behaviors of deep beams. The performance features of the deep T-beam were investigated, involving in strain distribution and principal stress trace using experimental tests. Different near surface mounted (NSM) reinforcement schemes were proposed for deep T-beams aiming at improving the shear capacity. The results show that the behaviors of deep T-beams dissatisfy the assumption of plane cross-section, and the ‘strut-and-tie’ model is applicable in such structures. The reinforcement systems can significantly relieve the strain concentration, mid-span deflection and crack width in deep T-beams, consequently improving the shear capacity range from 45 to 65%. The scheme is preferential for the reinforcement of deep T-beams when the applied angles, positions and lengths of CFRP bars are optimized based on the ‘strut-and-tie’ model.

“…Peng and Xue proposed a simple design method for the flexural capacity of prestressed and non-prestressed FRP reinforced concrete beams [10]. Atutis et al focused on crack width prediction and shear response analysis of the prestressed concrete (PC) beams [11]. Kara et al estimated the curvature, deflection and moment capacity of the reinforced concrete beams and predicted the moment-curvature relationship [12].…”

In view of the defects and limitations of the existing reinforcement methods, it is necessary to put forward a reinforcement method with better interfacial bond performance, more convenient construction and economical reinforcement. A new reinforcement technique with prestressed spiral steel wires was presented, and one control beam, three strengthened beams under monotonic loading were tested. Under the same initial prestressing level, the amount of reinforcement and different groove sizes, the flexural capacity, load-deflection relationship, crack and deformation of reinforced concrete beams were systematically investigated. Results show that the reinforcement technique can significantly improve the first-crack load, steel-yielding load, ultimate load of the beams, and improve the service performance of the strengthened beams. The high performance of the spiral steel wires is allowed for better utilization. The conclusions obtained in the study are of important reference value to direct the similar engineering practice.
