Swing Plates, Swing Beams, Swing Columns:

A revolutionary advance in Residential Base Isolation.

We invented Straddling Pendulum Technology. Patent US9951538

A new concept that overcomes many of the limitations of older base isolation designs. With the invention of the swing plate as an integral part of the swing beam, a new building component was born.

This seismic wave base isolation system has the purpose of absorbing seismic wave displacement energy in all directions. This unique design can scale up for very heavy loads or scale down to protect equipment inside buildings from destructive motion. This invention is particularly suited to reduce the initial shock of horizontal ground displacement.

This system has a simple form factor and is therefore easy to construct and easy to engineer and deploy. It requires no uncommon material and requires very little maintenance.

Shows a fully deployed system with many structural loads.

Buildings, Fluid Tanks, Electrical Substations

Straddling Pendulum Technology costs less. It has a simple form factor that is easy to build. It will handle larger ground displacements. It has many options for motion damping. It requires very little maintenance. It has a long life span with constant performance in extreme heat or cold because it contains no oils or rubbers and can be engineered to act as a Tuned-Mass Damper.

Shows the relationship between swing plate height and horizontal ground movement.

Therefore, you can design the plates to match the predicted ground thrust.

Below is an example of a six-story business center protected by six swing columns! The swing plates used are several inches thick steel plates with a leg distance of five feet!

This shows a Residential deployment.

This is just one example of a home being protected.

This shows a new vertical axis unit.

Shows a low-profile model used to protect a vaccine freezer in a hospital.

A very simple design to construct.

All flat steel plates are at right angles (very strong). They are then easily welded together to form the top and bottom walled components!
