摘要：
Four full-scale specimens were constructed and tested under reversal cyclic loading to study the seismic performance of interior GFRP-RC beam-column joints. The main test parameters were joint shear stress ratio and type of reinforcement (steel or GFRP). The performance of the specimens was evaluated in terms of hysteresis diagrams, mode of failure, strains in the reinforcement and energy dissipations. Test results indicated that the linear nature of GFRP materials resulted in lower residual damage in GFRP-RC beam-column joints compared to the corresponding steel-RC counterparts. Moreover, GFRP-RC joints withstood multiple cyclic loadings up to 8% drift ratio without exhibiting brittle failure.
