Beam Column Connection News Today

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 amoun...

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 ...
