Analysing ultimate strength of open box girders under bending and torque moment simultaneously

Tóm tắt

In this paper, the nonlinear finite element method is employed to predict the ultimate strength of open box girders model under combined loads of bending and torsion. The primary aim of this study is to investigate the ultimate strength characteristics of the  open box girders model under sagging bending moment and torque simultaneously. Results of theoretical and numerical analyses show that the bending moment and torque loads have different influences on the structural ultimate strength.
