The bridge girders weigh just tons for to foot spans and can be erected with locally-sourced common rental cranes, making them easy to deploy in most locations. Cut, fold, assemble, adhere, interlock, laminate, and shape the single sheet of card board using the least amount of material to provide the greatest amount of bearing capacity.

The system is composed of precast concrete panels over an FRP girder. Bridge forms can be beams and girdersarches, trusses or suspensions. Bridges not only serve a purpose, they can express meaning. The girder is reinforced with a hybrid composite containing thermoset resin, glass fiber and carbon fiber.

When you discover a bridge, look at its form, span, material, and travel location.

Design a bridge that expresses motion! The composite bridge withstood forces equivalent to more than 80 cars stacked on top of each other, and more than 5 times the HL 93 design load specified by AASHTO.

Activity 2 — Build and Test a Bridge A bridge is a simple span between two points. The beam will compress at the top edge and will be placed in tension at the bottom.

Review Bridge designers only consider structure when designing a bridge. Will its structure be heavy or light?
