Glass Bridge Concept –

Update: I seem to be losing….I wanted to use my rotating bridge between buildings but I was not sure how that could be prefabbed and installed.

The Happy Pontist found this site,, that holds competition for various challenges. I started on a concept last night and just submitted it. Don’t laugh too much but you can check it out here.

The competition is for a bridge that spans between building. I submitted a concept for an glass arch bridge. Glass bridges are not entirely new but they are best suited for locations that can keep a bridge completely in compression, which is what the buildings are doing. Here is my overview.

Glass Bridge Concept – Building to Building Challenge – DesignbyMany
(I literally found out about this competition, yesterday, so my concept is a little rough at this stage.)

Glass is one of the oldest manmade materials on Earth and is surprisingly strong in compression. Based on early concepts from previous designers, such as Thomas Heatherwick, a prefabricated Glass Bridge, completely in compression, is feasible for bridge designers.

The Building to Building challenge is ideally suited for arch bridges, because the two building act as solid abutments, keeping the arch in compression.

My thin shelled Glass Bridge concept uses a natural sustainable material, glass, and transforms it into a structural form. The bridge could be prefabricated and lifted into place between the buildings, in less than a day.

The outer shell of the bridge is an arched tubular rotated helix. The tubing would be used to regulate the temperature of the bridge by acting as a radiator in the winter and as a cooling structure in the summer. The complete structure could be prefabricated and lifted into place. The Helix could be clad with glass for cold weather climates or left open for warmer weather climates. (The rotated helix could also be prefabricated in two pieces and lifted into place around the Glass Bridge.)

A Glass Bridge shows how natural but innovative materials can be used in the bridge industry.

Concrete Beam and Column

I made a quick study of two concrete columns and a beam. Originally this model was used in my reinforced concrete design class to show how flexural and shear reinforcing is placed in a building element.
