The Effect of Subgrade Coefficient on Static Work of a Pontoon Made as a Monolithic Closed Tank

This article presents the effect of taking into account subgrade coefficient on static work a pontoon with an internal partition, made in one stage and treated computationally as monolithic closed rectangular tank. An exemplary is single, ready-made shipping element that can be used float for building. By assembling several floats together, structure form floating platform. Due to increasingly violent weather phenomena necessity ensure safe habitation people countries at risk inundation or flooding, amphibious construction could provide new solutions. calculations real purpose conducting research. Since it without any joint contact, concluded impossible water get inside. However, order exclude possibility filling water, its interior was filled Styrofoam. For calculations, variational approach finite difference method used, assuming condition minimum energy elastic deflection during bending, cooperation tank walls Styrofoam Winkler substrate Poisson’s ratio ν = 0. Based results, charts were illustrating change bending moments characteristic points analysed depending acting loads. The included hydrostatic loads upper plate ice floe pressure well buoyancy, stability metacentric height pontoon. aim study show finished product—a single-piece prefabricated designed use “houses water”.
