Harnessing Gravitational Force

Inverting its direction on structural spanning elements for beams, bridges, and buildings

Here Is How It Works

The Benefits

Reinventing the Beam

Supporting loads on beams in bending is inefficient

Rhombus

Use axial tension instead to manage those forces

Rhombus

Generate dynamic load balancing response

Rhombus

Redirect gravity from pulling down to “lifting up”

Rhombus

Fabricate lighter, stronger beams

Creating the Bridge Archetype of the Future

This new archetype transforms how bridges are constructed enabling faster, cheaper, and lower-carbon deployable bridges.

Live and dead loads are flipped to serve as their own load balancing prestress

Case study in failure

Why we need to invest in infrastructure R&D

Rhombus

We rely on 7 bridge archetypes, all developed prior to 1900

Rhombus

They are expensive to build and have large carbon footprints

  • ~75% of their structural mass is devoted to supporting just dead loads

  • Medium and long span bridges usually take years to construct

Rhombus

Baltimore’s Key Bridge collapse will take 3-4 years to rebuild and cost nearly $2 billion, with substantial negative economic impacts

Rhombus

“State of the art” in deployable bridges is WWII era Bailey Bridge

Inspired Architecture

Buildings as Human Architecture Analog

Apply how the human body is structured to buildings of the future:

Rhombus

Integrate equal parts tension members (ligaments, tendons) with compression members (bones) creating new architecture

Rhombus

Total building frame redirects and balances gravity loads

Rhombus

Structural members are optimized for efficiency and economy
