“…Li [85] measured the bond-slip behavior between coated steel bars and concrete by designing a full-beam test and conducted FEA using Ansys. When establishing the model, it was assumed that there was no slip between the coating and rebar, and only nonlinear spring elements were set at the interface between the coated steel bar and concrete to simulate the bond-slip behavior between steel bar and concrete.…”

With superior mechanical properties and workability, ultra-high-performance concrete (UHPC) has been utilized extensively in engineering projects. To gain a comprehensive understanding of the bond behavior of UHPC or ultra-high-performance fiber-reinforced concrete (UHPFRC), researchers studied the factors influencing the bond-slip between rebar and UHPC or UHPFRC over the past few years. The literature-proposed ultimate bond strength formulas and the bond-slip constitutive model between rebar and UHPFRC are analyzed and compared. Based on the bond test database of UHPFRC, the results indicate that UHPFRC strength, relative concrete cover thickness, relative bond length, and steel fiber volume content are the primary parameters influencing the ultimate bond strength between rebar and UHPFRC. In the bond-slip constitutive model, the nonlinear ascending and linear descending model is more accurate than other models. This paper concludes by discussing the shortcomings in UHPC or UHPFRC bond research and predicting the future research trend.

“…The results show that the coupling corrosion of main rebars and stirrups further aggravate the decline of bond performance of stirrups with comparison to only considering the corrosion of main rebars. As a result, the factors affecting rebar-concrete bond performance can be summarized, including concrete strength, rebar diameter, cover thickness, anchorage length and stirrup ratio (Kang et al, 2020; Khaksefidi et al, 2021; Li et al, 2020).…”

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.

“…e steel-reinforced concrete structures have been widely used in practical engineering due to their excellent durability, economical advantage, and antiseismic performance. e experimental research shows that there is a bond-slip problem between profile steel and concrete in steel-reinforced concrete structures, and the bond-slip problem has a significant adverse effect on the working performance of the steel-reinforced concrete structure [1][2][3][4][5][6][7][8][9][10][11][12]. At present, domestic and foreign scholars have made many achievements in the design and calculation theory of steel-reinforced concrete, but there are still many problems that have not yet reached a consensus.…”

The bond-slip damage of the interface between profile steel and concrete is the key point of steel-reinforced concrete structure. This paper is based on the statistical analysis of a large amount of experimental data and the distribution characteristics of bonding stress on the bonding surface of the profile steel and concrete, and the conversion rules between the three parts (chemical bonding force, frictional resistance, and mechanical interaction) of the bond force are obtained. According to the mutual conversion rules of the three parts of the bonding force on the steel-reinforced concrete bonding surface, a mesomechanical model based on the spring-friction block element is established. Taking into account the discreteness of concrete performance on the bonding surface and the randomness of defects, using the stochastic damage theory, a constitutive model of stochastic bonding damage on the steel-reinforced concrete bonding surface is established. The comparative analysis with the results of a large number of steel-reinforced concrete pull-out tests shows that the model can reasonably reflect the damage characteristics of the steel-reinforced concrete bonding surface.
