- •
FE models for partially encased composite (PEC) columns are developed and verified.
- •
Failure mechanism of steel elements in PEC columns is revealed.
- •
Factors affect buckling and post-buckling behavior of steel flanges are investigated.
- •
Formulas of critical and post-buckling stresses are proposed.
- •
Expressions for stress-strain relationship are developed.
