Abstract

In this paper, we present two simple arrangements of portable tent structures for flood protection. In the first, an inflated cylinder lifts the top of the textile as the water level rises, while in the second the textile supporting the water pressure of the tide is hung on a steel framework and is filled with water previously. We give a numerical solution for the nonlinear system of equations of the compatibility and equilibrium conditions, and also present a complete analytic solution to the boundary value problem of the shape of an inextensible, weightless, prismatic textile, similar to the sessile drop problem. After discussing the mechanical behavior of the structures, different geometries capable of withstanding a certain water height are determined by a software developed for this specific purpose enabling the design for optimum. Furthermore, the basic rules of thumb are also formulated, aiding the preliminary conceptual design.
