Research Abstract

The collapse behaviour of the hybrid steel girders under bending is studied with the FEM analyses. The results of the analyses indicate that the flange vertical buckling is the major collapse pattern of the hybrid girders.
It is also found that the Basler's formula is not appropriate to verify flange vertical buckling.
