The study investigates the cyclic bond behavior of FRP bars from four key parameters—bar diameter, embedment length, concrete strength, and rib geometry—leading to the development of a unified bond stress–slip constitutive model and hysteresis framework. Validated through systematic pull-out tests, the model accurately captures interfacial degradation mechanisms under cyclic loading and provides a reliable foundation for simulating FRP-concrete interaction in seismic applications, enhancing the precision of performance-based structural design.
