文摘
- •
Inelastic LTB resistances of cellular beams are investigated by Nonlinear FE models.
- •
Shear effects and geometric parameters of practical cellular beams are considered.
- •
With short beams and shear loads, LTB failures may interact with the local failures.
- •
The resistance of EC3 design requires a correction to ensure its conservative.
- •
A correction factor based on the parameters reflecting shear effects is proposed.
