This study aims to investigate the seismic behavior of bidirectionally loaded non-ductile beam-column corner joints with and without minimum joint transverse reinforcement. Four full-scale specimens were built and tested; test variables were applied a minimum joint transverse reinforcement and a high-performance fiber-reinforced cementitious composites (HPFRCC). The energy dissipation capacity and cyclic strength retention capacity were estimated for each test specimen. During testing, the longitudinal reinforcement yielding, and the joint shear strain were monitored. The results revealed that the application of HPFRCC is an effective means to improve the seismic behavior of non-ductile corner joints irrespective of the existence of minimum joint transverse reinforcement. |
