- •
Twenty-one SRHC columns were tested under simulated earthquake loading.
- •
SRHC columns with multiple stirrups and commonly used structural steel ratio have excellent seismic behavior.
- •
Larger effective confinement index of stirrups leads to better deformation and energy dissipation capacity.
- •
Multiple stirrups should be adopted in SRHC columns to give full play to structural steel.
- •
Studs have positive effect on seismic behavior of SRHC columns after cover concrete spalling.
