- •
GJ steel is used in large projects like National Olympic Stadium and Canton Tower.
- •
Eight doubly symmetric welded section beams were tested under a concentrated force.
- •
Numerical simulations and parametric studies were carried out as well.
- •
The results of tests and parametric studies were compared with different design codes.
- •
Proper design methods for the overall stability of Q460GJ steel beams are recommended.
