Abstract:
Four-point bending tests were conducted on five full-scale specimens to investigate the flexural performance of bolted-side-plated (BSP) reinforced concrete (RC) beams. The influence of different local buckling restraining measures (such as halving bolt spacing, welding steel bars, and anchoring steel angles along the upper edges of the bolted steel plates) on the cost, failure mode, strength, stiffness, ductility, local buckling, and relative slippage of the BSP beams, was studied in detail. An analytical model was developed to evaluate the flexural bearing capacity of BSP beams. The outcomes showed that: 1) the BSP technique could significantly increase the flexural strength and stiffness of RC beams; 2) the buckling restraining measures could further improve the flexural strength and the ductility while also suppressing the local buckling and decreasing the relative slippage on the steel-concrete interface; 3) a comparison between the theoretical and experimental results validated the feasibility and accuracy of the analytical model.
