2023年3月1日 · Under the given impact energy, as the stirrup ratio increases, the midspan peak and residual displacement are reduced. More stirrups are activated while stirrup peak strains decrease in the shear region. The increasing stirrup ratio enhances the integrity and overall rigidity of the beams, which is more effective at higher velocities.

2022年7月1日 · The numerical investigation in this study deals with the bond performance of BFRP bar embedded in concrete with/without BFRP stirrups by direct pull-out method. In the numerical model, the heterogeneous nature of concrete and geometry of surface profile of the main BFRP bar were considered.

2023年11月13日 · This research aims at investigating experimentally and theoretically the influence of using basalt fiber-reinforced polymer (BFRP) stirrups and bars on the performance of shear of beams.

2025年3月1日 · The BFRP bars-RC beams' torsional strength, ductility, and deformation capacity exhibit a remarkable size effect, with the torsional strength decreasing by 52.32 % when the beam height is increased from 300 mm to 900 mm. Increasing the stirrup ratio can weaken the beams' size effect, but the size effect will not be eliminated.

This study established and validated the 3D modeling approach of Basalt FRP (BFRP) reinforced concrete beams with different stirrup ratios. Numerical simulations were performed under different impact energy.

2023年12月27日 · The shear behavior of basalt fiber–reinforced polymer-reinforced seawater–sea sand concrete (BFRP-SSC) beams was investigated experimentally. The effects of several factors, including stirrup diameters (8, 10, and 12 mm), stirrup spacings (100, 125, and 150 mm), and shear span-to-depth ratios (1.55, 1.95, and 2.35), were considered.

This study revealed that the shear strength prediction of BFRP reinforced beams with and without BFRP stirrups are in good agreement with shear characteristics of RC beams with other FRP bars (GFRP, CFRP, and AFRP).

In this study, the preparation process of basalt fiber-reinforced polymer (BFRP) bar reinforced shield tunnelling segment (BSTS) is described in detail against the background of shield tunnelling segment actually used in engineering.

2022年12月1日 · The dynamic to static stiffness ratio and ultimate load ratio is reduced following the growth of BFRP bars area ratio (max. gap up to 56 % and 25 %) and fire time (max. gap up to 15 % and 20...

2023年3月1日 · The dynamic to static stiffness ratio and ultimate load ratio is reduced following the growth of BFRP bars area ratio (max. gap up to 56 % and 25 %) and fire time (max. gap up to 15 % and 20 %). Therefore, specimen design prioritizes …
