| Abstract: |
| In this paper, a space displacement
field on considering the deck local buckling for the plate truss composite is constructed by
using transverse finite stripe. The Update Lagrangian formulations of deck beam finite element
in transverse stripe are induced based on the three dimensional continuum virtual work
incremental equilibrium equation, and the effect of large deformation is taken into consideration.
This method has high accuracy and less degrees of freedom, especially for geometric non
linear analysis of large plate truss composite structure. In the end of this paper. Guang Dong Xi
Jian plate truss composite structure model steel bridge is calculated, the results are very close
approximation to the test data. |
