Abstract
This paper highlights areas of inaccuracy in current
modelling techniques for bridge decks with wide cantilevers.
The upstand grillage model is assessed by comparing its
behaviour with that of a three-dimensional finite element
model. Recommendations are made for the implementation
of such a technique. The paper concludes with a comparison
of results from analyses of a bridge deck using the standard
and upstand grillage analogies and the finite element
method.
