Latest Patents
Joseph Plecnik holds a patent for a "Seismic evaluation method for underground structures." This method involves modeling the behavior of underground structures, such as storage tanks, under seismic loads. The process includes constructing separate finite element models for the ribs, tank, and fill material. The fill material model consists of three-dimensional solid "brick" elements, while the tank model is made up of three-dimensional plate/shell elements. The rib model comprises beam elements, with nodal points corresponding to the tank shell's edge. The model is designed to be joined to the soil model through radial link elements, and spring elements may be added for stability. A dynamic vertical or horizontal forcing function from an earthquake is applied to the model, allowing for the analysis of stress and displacement results.
