Abstract
This work presents two proposals for spanning the Galician rías. The rías are the
equivalent to the Scottish firths or the Scandinavian fiords, thus long-span
bridges are required to communicate both sides of that physical barrier.
Additionally, the multidisciplinary approach applied in the design of these
proposals that have been developed in the last decade by the Structural
Mechanics Research Group is explained.
Keywords: suspension bridges, sensitivity analysis, optimum design, advanced
visualization, aeroelasticity.
1 Introduction
Galicia is the name of the Spanish region located in the northwestern corner of
the Iberian Peninsula (see figure 1). This region does not have high mountains
nor large rivers, the main characteristic of the Galician physical geography is the
existence of \“rias”. The rias are sea waters that have advanced deep into the land,
in the mouths of some small rivers (see figure 2). Thus, there are two different
ways to understand the rias as a frame for the territory: on one hand as sea
masses that have penetrated into the land and on the other hand they are also
peninsulas that have advanced into the Atlantic ocean. This fact has given birth
to a very special and delicate environmental balance that hosts important
industries related with the seafood. At the same time, due to their characteristics
as natural harbours, they also host crucial industrial and commercial activities
and, therefore, the two main metropolitan areas around the cities of La Corunna
in the north and Vigo in the south (marked with yellow frames in figure 2) are
located around the \“Rias Altas” and the \“Ría of Vigo”, respectively. The
existence of the rias has constrained both the road and railway networks in
