This study numerically investigates the cyclic behavior of glass fiber-reinforced polymer (GFRP) reinforced concrete exterior beam-column (T-BC) connections (GFRP-RC T-BC connections) with varying amounts of transverse reinforcement (TR) in the connection panel. The amount of TR required to provide adequate confinement and shear strength to the GFRP-RC T-BC connections has not yet been fully understood. The primary objective of this study was to evaluate the effects of TR configuration and amount of TR on the load-drift ratio response, strain distributions and shear strength of the GFRP-RC T-B...

This paper proposes two novel reinforcement details for glass fiber-reinforced polymer (GFRP) reinforced concrete (RC) exterior beam-column connections. Four RC exterior beam-column connections with different connection details (SH-bend, GH-bend, Z-bend, and U-bend) were tested under reversed cyclic loading. The two conventional connection details (SH-bend and GH-bend) comprised three 90-degree hooked bar anchorages for longitudinal reinforcement of the beam and four rectangular stirrups (steel or GFRP) within the connection region. In the two novel connection details (Z-bend and U-bend) propo...
