GRILLAGE ANALYSIS TUTORIAL for Bridge Decks
2019-3-28 · If a simple two dimensional (2D) grillage is used then the bending effects from the cantilever will be resisted by torsion in the edge beam. This will overestimate the torsion in the edge beam and underestimate the bending in the deck. Some grillage programs allow the centriods of the members to be offset from the 2D plane (as shown in Fig.6).
