“…In recent years, there has been extensive research at home and abroad on the mechanical properties of PSRHSCBs (Akiyama et al, 2012;Wu et al, 2019;Jiang et al, 2021). Ji et al (Ji et al, 2011) carried out simulations and analyses on seven PSRCBs, and the influence regularity of various parameters on the monotonic bending moment-curvature curves of the section and the monotonic load-displacement curves of the components was obtained, finally, the ductility formula and restoring force model for this kind of beams were established systematically by statistical regression.…”

To study the seismic behavior of steel-reinforced high-strength concrete composite beams with bonded tendons (PSRHSCBs) under low cyclic loading, 13 PSRHSCBs were designed with the main parameters of the span-to-height ratio of beams (L/H), the cubic strength of concrete (fcu), the eccentricity of H-shaped steel (eH), the volume stirrup ratio (pv), the longitudinal reinforcement ratio (p), and the tension control stress of tendons(σcon). Using the simplified bilinear constitutive model of steel and the nonlinear constitutive model of high-strength concrete, and introducing plastic damage of concrete, fine finite element models were established with ABAQUS software. 11 similar test specimens were conducted by above modeling method, by comparing existing test curves and numerical simulation curves, both of them match well, which verified the validity of the modeling method. Subsequently, parameter analysis for 13 PSRHSCB specimens was performed, and the influence regularity of different parameters on the seismic behavior of this kind of composite beams was obtained. The results show that hysteretic curves of this kind of composite beams are full, and the failure mode is manifested as bending failure. The ultimate load, the energy dissipation capacity and the ductility coefficient of specimens can be improved significantly by increasing pv, on the contrary, the energy dissipation capacity and the ductility coefficient decrease gradually by increasing fcu. The stiffness degradation of specimens significantly slows down with the increasing of L/H and σcon, and the decreasing of eH. Finally, the trilinear skeleton curve model and the restoring force model are established by statistical regression, and the corresponding seismic design suggestions are given, and these can provide theoretical support for the seismic design of such composite beams in actual engineering.

“…Akiyama et al [9] conducted bending tests on a new type of prestressed high-strength reinforced concrete pile and demonstrated that carbon-fiber sheets and concrete infilling could effectively increase the flexural capacity of this type of piles. Wu et al [10] reported that PHC piles reinforced with hybrid glass fiber-reinforced polymer (GFRP) bars and deformed rebars showed much higher flexural capacity and deformation capacity.…”

“…Furthermore, Wu et al. [17] carried out a full-scale experimental study on the flexural strength and behavior of PHC piles reinforced with GFRP bars and deformed steel bars, respectively. The results showed that piles reinforced with GFRP bars had much higher flexural capacity than those reinforced with deformed steel bars, and increasing the hybrid reinforcing bar ratios could significantly enhance the post-cracking flexural strength and stiffness of PHC piles.…”
