Secondary Stiffness Devices for Structural Systems

Invention SummaryThis invention adds additional stiffness to Buckling Restrained Braces (BRB), which support steel beams in construction applications. This product enhances BRBs by adding a steel compression plate (Fig.1) with stiffeners and secondary tension straps (Fig.2). These both improve the stiffness of regular BRBs in order to help control the...

Expanded Polystyrene (EPS) Geofoam Bridge Support System

Invention SummaryThis technology is a method of using Expanded Polystyrene (EPS) blocks to support relatively lightweight bridge structures, primarily 2-lane single-span highways and pedestrian bridges. The EPS accomplishes this by acting as the support embankment. This use of EPS eliminates the need for intermediate or deep foundation systems, reduces...

Perforated Plate Seismic Dampers

Invention Summary A novel energy efficient absorption device used to dissipate energy and thereby reduce damage of a structure due to applied external and internal forces/stress. It is composed of a single steel plate shaped to have four "nodes" or fuse points of reduced area. As a structure experiences seismic accelerations that produce inter-story...
