Abstract |
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. |
