| Summary: | Partially-encased composite beam-columns subjected to axial compressive and transverse
loads were analyzed using a proposed analytical method, finite element modeling and
international approaches, including ACI-318, AISC-LRFD and Eurocode4. In addition,
flexural stiffness (EI) was predicted using the recommended formulas in ACI-318 and EC4.
The results were compared with experimental data to verify of the reliability of these results.
The analysis proved that the proposed method could be used for design the partiallyencased
beam-columns. Research results also indicate that this method gives much close
solution to experimental data. The behavior and deformation shape of specimens were
close to those found using FEM. The predicted EI from EC4 was reliable in calculating the
bending moment using the proposed method while a significant difference in deflection
values was pronounced using predicted EI from ACI formula. From calculations, it was
found that the ACI-318 approach is accurate and reliable in the design of partially-encased
beam-columns.
