| Abstract | Two scale models of prestressed pseudo slabs were tested and the
results analysed to study their load distribution behaviour and to formulate some empirical expressions or rules for evaluation of the elastic
parameters of such multibeam bridge decks.
Bridge Slab 1 incorporated precast prestressed solid box-sections
with shear keys of in-situ concrete and varied amounts of unbonded mild
steel in the transverse direction.
Bridge Slab 2 consisted of precast prestressed solid box-sections,
wider than those of Slab 1, with shallower shear keys and shear dowels.
The slab closely conformed to a form of construction adopted by the
Concrete Products and Aggregate Co., Ltd., Bangkok.
Results for Slab 1 showed that the mild steel reinforcement in the
transverse direction has no effect on load distribution behaviour up to
the elastic design loads, beyond which it does contribute to the transverse moment of resistance of the slab. The results of this slab
> enabled the formulation of definite rules for evaluating the flexural
and torsional parameters for such slabs.
In the case of Slab 2 it was found that the depth of shear key was
inadequate for transference of moment between the longitudinal members.
Application of articulated plate theory for analysis of this type of
slab is more reasonable, although the resulting design will be somewhat
on the conservative side. |
