This dissertation proposes a model of metrical analysis under a
constraint-based framework, namely, Optimality Theory. This proposal works
on grids and constituents organized in a multidimensional plane ruled by
phonological principles, which control the projections onto a metrical
grid. This approach aims at translating the properties of main stress of
those languages, which deal with prosodic word final elements as
extrametrical ones and also with those languages with the trisyllabic
window condition. This proposal will demonstrate that it is not necessary
to make any reference to such aspects, since they will be naturally derived
from the constraint hierarchy. The formulation of this model will be a
priori subsidized by the main stress pattern of Brazilian Portuguese
non-verbs and then it will be applied to other languages.
