“…Study on the contribution of transversal reinforcement to the elongated joint with a headed [7] and bending of the hook reinforcement [13], the results obtained show that transverse reinforcement is effective in increasing the strength of anchoring on head reinforcement [5]. This result supports Darwin's research [8], with the transverse reinforcement installation, there is an additional strength of 25% [8].…”

The behavior of reinforced concrete structures depends on sufficient bond strength between concrete and reinforcing steel. The perfect bond between the reinforcement surface and the concrete makes the transfer force work well. In this experiment, several forms of bars overlapped in the concrete and then tested pullout directly. This experiment is to get the tendency of the bond stress patterns that occur in overlapping bars. Another result of the study is the failure pattern of each specimen. The specimen size is 150í—150í—150 mm. In the center of the concrete cube is rib two overlapped bars. The reinforcement used plain and two ribs types of bars surface. The compression of concrete used is a minimum of 25 MPa. Furthermore, the specimen was subjected to a pullout test loaded in stages with 22 kN/minute speed. Loading stopped after the sample has collapsed. The pullout test uses the ASTM C234-91a standard. The failure pattern of plain reinforcement specimens with diameters of 12 mm, 16 mm, and 19 mm is a pullout or a slipped. The specimen with deform bar diameter 13 mm, 16 mm, and 19 mm occurs in splitting failure. The pullout test result, all samples in connection not yielded yet. The results show that the higher the bar diameter's development length, the higher the bond strength. The bond stress of the plain bar is smaller than the deform bar.

The glass fiber reinforced polymers (GFRP) bars are considered as an alternative to steel reinforcement in certain structures cases due to their non corrosive aspect. Perhaps, they exist with different surface treatment helically wrapped (GFRP-HW) and sand coated (GFRP-S). Thus, each rebar type is performed by a particular bond behavior with the concrete and it affects the concrete crack formations. In the first part of this paper, an experimental and analytical study of the bond behaviour between the (GFRP), rebars and concrete were carried-out. Pull out test tests have been applied on concrete cylindrical slabs in order to identify experimentally the bond behaviour between the self-compacting concrete and GFRP. Various parameters were taken in account in this experimental study: the rebar diameters, the concrete age, and the rebar roughness. Based on the experimental results, the failure mode of the bond specimens, the variation of the bond load, and the bond-slip variation are analyzed. Two failure modes of the GFRP rebars were experimentally identified: the pull-out failure mode and the splitting one. According to the experimental data, it was proven that the GFRP-S rebars and the steel ones exhibit a more bond performant than that of the GFRP-HW rebars. In the second part, an analytical identification of the BPE and the CMR models was established. Subsequently, a tension tie model was extended analytically in order to predict the crack patterns of concrete elements reinforced with the GFRP rebars and steel rebars. The expressions of the cracking parameters issued from the tension tie model have been developed. It can be deduced that the GFRP-HW and GFRP-S reinforced concrete element exhibits a longitudinal strain less than that of the steel reinforcement case. Hence, the GFRP reinforced element undergoes cracks that are characterized by more important width measurements than those of the cracks deduced from the case of the reinforced steel element. Finally, the stress-strain analytical diagram of a GFRP tension member has been plotted and compared to the steel tension element.

In light of the increasing demand for sustainable building materials, the effectiveness of bamboo utilization in various fields has become the object of scientists' close attention. The increased interest in bamboo is explained by its sustainable characteristics, which make it the most preferred material for environmentally friendly and costeffective construction compared to conventional ones. Applicability of bamboo is vast and diverse: from decoration and furniture to structural members and reinforcement. Due to the low price, rich resources, and high elasticity, bamboo culms have also been used as an alternative to steel reinforcement in concrete structures. Extensive research has been done to assess feasibility of bamboo reinforcement in structural elements made of concrete. This article discusses the mechanical properties of three types of structural bamboo reinforced concrete (BRC) beams. Existing original papers on the mechanical behaviour of structural BRC members were studied, and the fundamental properties including typical failure modes, reasons of failure, load-displacement relationships, and influencing factors were discussed and described. Observations and conclusions of the review will contribute to deep understanding of structural feasibility of BRC beams and serve as a base for future research.
