- •
Web-post buckling of protected cellular steel beams in a fire was investigated.
- •
Temperature gradient in web-post affects behaviors of partially protected beam.
- •
Principle compression stress in web-post decreased suddenly when web-post buckled.
- •
Stress at web-post center could be in tension due to large out-of-plan deformation.
