“…Note: The naming method of specimen, for example, the specimen "A-1-451500-1" represents the first specimen in group "A-1", where the diameter of steel strand is 4.5 mm, the lap length is 15d, and the spacing of transverse steel strand is 0 mm. T a (kN) is the peak load, τ a (MPa) is the average bond stress calculated by formula (3), and l LP (mm) is the slip amount calculated by formula (2). ϕ (%) is the strength conversion rate for HSSSWM.…”

“…One of these materials is Engineering Cementitious Composites (ECCs). By adding fiber materials to ECCs, the fiber bridging action prevents the opening and propagation of cracks, resulting in good strain hardening behavior and multiple cracking performance compared to ordinary concrete in tension [1][2][3][4]. This improved ductility, deformation ability, and energy absorption ability of the structure [5,6].…”

“…Xu et al [13] artificially rusted the reinforcement in the specimens using the constant current method, and investigated the effect of corrosion on the lap-spliced performance of the reinforcement through uniaxial tension tests. Al-Quraishi et al [2] investigated the tension lap-spliced length of reinforcing bars embedded in reactive powder concrete (RPC). The results of the study showed that the bond strength of the spliced bars increased with the increase in lap length up to a certain point, beyond which it decreased.…”

To investigate the mechanical properties of high-strength stainless steel wire mesh (HSSSWM) in Engineering Cementitious Composites (ECCs) and determine a reasonable lap length, a total of 39 specimens in 13 sets were designed and fabricated by considering the diameter of the steel strand, spacing of the transverse steel strand, and lap length. The lap-spliced performance of the specimens was tested through a pull-out test. The results revealed two failure modes in the lap connection of steel wire mesh in ECCs: pull-out failure and rupture failure. The spacing of the transverse steel strand had little effect on the ultimate pull-out force, but it restricted the slip of the longitudinal steel strand. A positive correlation was found between the spacing of the transverse steel strand and the slip amount of the longitudinal steel strand. With an increase in lap length, the slip amount and ‘lap stiffness’ to peak load increased, while the ultimate bond strength decreased. Based on the experimental analysis, a calculation formula for lap strength considering the correction coefficient β was established.

In this paper, 3D finite element simulations were conducted for lap-spliced ultra-high-performance concrete (UHPC) beams using ABAQUS software. Based on the concrete damaged plasticity (CDP) model, the plastic damage factor was introduced to simulate the material properties of UHPC. The nonlinear characteristics of the steel bar and UHPC were considered, and the bond–slip constitutive relationship was selected to evaluate the bond–slip between the lap-spliced steel bar and UHPC. The simulated load–deflection curve, peak load, bond strength, and failure mode were in good agreement with the experimental results. The verified finite element model was used to analyze the parameters of the lap-spliced UHPC beam. The effects of lap-spliced steel bar diameter, stirrup spacing of non-lap segment, and shear span ratio on the mechanical properties and bond properties of the lap-spliced UHPC beam were studied. This study can provide a reference for the future simulation and design of lap-spliced UHPC beams.

“…Some scholars have studied the interaction between RPC and steel bars. Al-Quraishi et al [10] investigated the influences of the number of transverse steel bars on the tension splice intensity of steel bars embedded in RPC. The results showed that the tension splice strength increased with the number of steel bars.…”

In this paper, the steel bar was used to prepare steel bar reactive powder concrete (SBRPC). The three-point bending test was adopted to investigate the effect of the number of steel bars on the flexural strength of SBRPC. The acoustic emission (AE) was used to monitor the fracture process of SBRPC in real time. In addition, the parameter RA and AF ratio (RF) was defined to analyze the distribution of shear cracks and tensile cracks during the fracture process. The experimental results showed that with the increases in the number of the steel bar, the flexural strength of SBRPC gradually increased. The fracture stage of SBRPC can be accurately divided according to the curve slope change in hits and cumulative counts. Moreover, the early warning of SBRPC damage can be realized by observing the amplitude of the AE amplitude value. The dynamic changes in the rising angle (RA) and average frequency (AF) values can be used to determine the cracks mode and fracture mode. Based on the results of RF analysis, adding steel bars will improve the proportion for tensile cracks during its fracture process.
