Behaviour and Design of Hybrid Steel Girders

通过有限元分析，研究了混杂钢梁在弯曲荷载作用下的倒塌行为。分析结果表明，翼缘垂直屈曲是混合梁的主要破坏形式，并发现用Basler公式来验证翼缘垂直屈曲是不合适的。

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.
