- Abstract:
- Low-cycle repeated tests were carried out on four T-shaped concrete columns equipped with HRB500 steel bars, and the failure mode, bearing capacity, ductility, stiffness degradation, and hysteresis characteristics of the HRB500 steel bars and the matched high-strength concrete T-section special-shaped columns were analyzed. , energy dissipation capacity and other seismic performance indicators, the influence of hoop eigenvalues and axial compression ratio on the seismic performance of T-section columns is discussed. The research shows that: T-section concrete special-shaped columns with HRB500 reinforcement work well with high-strength concrete , has a high load-bearing capacity, and its ductility and energy dissipation capacity and other seismic performance indicators are good, and can be used in special-shaped column structures in strong earthquake areas.
