Abstrakt:

Premature corrosion of reinforcing steel is a significant concern for steel-reinforced concrete (RC) structures, often leading to deterioration before reaching their design life. To address this issue, glass fibre-reinforced polymer (GFRP) bars have proven effective as a corrosion-resistant alternative in structural elements such as beams, columns, and slabs. Recent studies have shown that concrete shear walls reinforced with GFRP bars exhibit acceptable performance in terms of ultimate strength. However, compared to conventional steel reinforcement, limited data exist regarding their cracking, deformation, creep susceptibility, long-term performance, and cost. In this paper, a parametric study using a finite-element analysis model, validated against experimental data, was conducted to evaluate the effect of common design variables in GFRP-reinforced concrete shear walls. The study identified optimal design solutions where GFRP-reinforced walls outperform conventional RC walls. The analysis revealed that optimal GFRP designs cost approximately 1.5 times more than steel-reinforced walls, with deflection and crack width emerging as critical factors influencing design feasibility. The use of high-strength concrete was found to have minimal impact on the feasible design region, while bond strength between GFRP bars and concrete significantly influenced crack width and overall performance. Furthermore, creep rupture was determined not to be a critical concern under typical loading conditions. The results highlight that feasible GFRP designs are governed by service conditions, whereas ultimate strength remains the primary constraint for steel-reinforced walls.
