DAB510 WEEK 3: Fabrication - Structural Elements

To refine the structural elements into a plausible design, we accepted that we needed a significant footing to support the 5m cantilever. Steal was chosen as a material best suited to support such a larger force, while also responding to the materiality of the bridge itself. I-beams were introduced to weight of the beam. A silicon/rubber like joint was introduced to offset any cracking in the glass from expansion and contraction, but perhaps a different type of technology can also be used in its place.

 Flooring System Detail

The system encorporated in the skin of the Node was a little more complex to solve. Despite the difficulty in manufacting a very precise and unique components (everything is individually size) we decided to choose a design which saw glass panels slot in between the metal framework, allowing plenty of natural light, but also sufficient shade to the interior.

The materials used in the skin of the facade also payed homage to the techtonic nature of the bridge. Rivited steel and glass were incorporated to mimic the appearance of the cascading steel structure which engulfs you as you walk or ride anywhere near the bridge. It is designed to diminish the experience of the user and celebrate the overwhelming scale of the Storey Bridge.
