文摘
- •
Six square FRP–HSC–steel DSTCs are tested under axial and cyclic lateral loading.
- •
Effects of axial load, column aspect ratio, steel tube size and concrete fill are studied.
- •
Square DSTCs exhibit ductile behavior under combined axial compression and cyclic lateral load.
- •
An increase in axial load and a decrease in aspect ratio result in a decrease in the lateral drift capacity.
- •
Concrete-filling the inner steel tube leads to a significant increase in the lateral drift capacity.
