Abstract

Inflatable flood and storm-surge barriers based on existing pneumatic dam technology promise several economic and environmental advantages over traditional structures such as sea walls. The numerical modeling of such structures must consider the complex hydrodynamic loads, the flexibility of the structure, and the ensuing fluid-structure interaction. With regards to form, to date, studies in the literature have only considered simple semi-cylindrical geometries. This work is motivated by the hypothesis that the barrier's resistance to fluid loads can be optimized by improving upon this typical design, for example, by introducing double curvature (corrugations). To this end, this paper reviews a suitable finite element model and then presents a parametrization of the design space for this type of pneumatic structure, based on the analytical solution of the volume maximization problem for cylindrical pneumatic membranes. The qualitative behavior of some of these geometries under a hydrostatic load is assessed numerically.
