This study recommends new simplified equations for the transverse moment and shear force at the base of the cantilever overhang due to applied vertical truck loading. This was made possible through a parametric study that utilized finite-element modelling on bridge deck cantilevers with variable lengths and slab thicknesses. Different end stiffening arrangements were considered that are encountered in practice, and included but were not limited to the PL-1, PL-2 and PL-3 New Jersey-type barriers walls, a PL-2 parapet, and a curb supporting intermittent steel posts carrying a guardrail. The barrier length changed from 3 to 12 m and the cantilever length ranged from 1.0 to 3.75 m. Further to the empirical expressions that had been developed, the study is supported by tables that were developed to readily design the cantilever slab, based on vertical loads due to vertical truck loading, as well as horizontal railing loads against the barrier wall.

Concrete Bridge Decks

Post-tensioned continuous voided concrete bridge decks are widely used in the Province of Ontario. These bridge deck designs are generally based on one-dimensional analysis. The longitudinal moments are usually calculated by considering the deck as a wide beam, and the transverse moments in midspan and at the intermediate supports are evaluated by treating those portions of the bridge as a transverse beam and a frame respectively.To examine more precisely this two-dimensional structural behavior under various loading conditions, the recently designed Highway 403 underpass at Winston Churchill Boulevard in Mississauga, Ontario, was analyzed using the readily available ICES STRUDL-II finite element program.This paper describes the ICES STRUDL-II finite element modelling and analysis procedures, the results obtained, and the comparisons with conventional calculations.
