Macro synthetic fiber-reinforced concrete can partially or completely replace steel bars, reduce construction costs, and improve durability.
However, its synergistic performance with longitudinal bars, especially its structural response under long-term loads, still needs systematic experimental verification.
Existing research focuses more on short-term performance and lacks experimental data on creep, shrinkage, and long-term evolution of cracks.
This study aims to fill this gap and provide a basis for related engineering designs.
