Seismic Evaluation Method For Underground Structures
US Patent:
6397168, May 28, 2002
Filed:
Jul 30, 1999
Appl. No.:
09/363858
Inventors:
Joseph Plecnik - Long Beach CA
Albert F. Dorris - Edina MN
Robin L. Berg - Hudson WI

Assignee:
Xerxes Corporation - Minneapolis MN
International Classification:
G06F 1710
US Classification:
703 2, 703 7, 703 10
Abstract:
A method for modeling the behavior of an underground structure such as an underground storage tank under seismic loads includes the steps of constructing separate finite element models for the ribs, tank and fill material. The fill material model comprises a plurality of three-dimensional solid âbrickâ elements. The tank model comprises a plurality of three dimensional plate/shell elements. The rib model comprises a plurality of beam elements. The nodal points for the beam elements correspond to nodes defining one edge of the tank shell. The tank/rib model is preferably joined to the soil model through a plurality of radial link elements between the brick and shell elements. Spring elements may also be added for stability. A dynamic vertical or horizontal forcing function from an earth quake is then applied to the model. Stress and/or displacement results from horizontal and vertical forcing functions may then be combined if desired.
Hazardous Material Containment System
US Patent:
5588461, Dec 31, 1996
Filed:
Apr 8, 1994
Appl. No.:
8/225376
Inventors:
Joseph M. Plecnik - Long Beach CA
Assignee:
Philipp Brothers Chemicals, Inc. - NJ
International Classification:
B67D 532, G01M 318
US Classification:
137312
Abstract:
A system is provided for containing material leaks which occur while a shipping container is being loaded or unloaded. The system includes portable dome that is placed on top of a shipping container, covering the container's inlet or outlet valves. If a leak is detected, the flow of material is stopped, and the leaked material is either absorbed or neutralized.
