SUMMARY

The discussion focuses on constructing a small-scale cable-stayed bridge with a beam design, emphasizing the need for effective joints and fixtures to secure wood components. Participants explore various options, including glue and angle brackets, while expressing concerns about the durability of these materials. Additionally, they seek solutions for attaching 0.7mm diameter wire to the deck and pylon, dismissing glue as a viable option and considering alternatives like tie wraps. The conversation highlights the importance of selecting appropriate fixtures for structural integrity.

PREREQUISITES
  • Understanding of beam bridge construction principles
  • Familiarity with materials such as wood and metal fixtures
  • Knowledge of cable-stayed bridge design elements
  • Experience with fastening techniques and hardware options
NEXT STEPS
  • Research the use of angle brackets in bridge construction
  • Explore alternative fastening methods for wire attachment
  • Investigate the properties and applications of different adhesives
  • Learn about structural integrity assessments for small-scale bridges
USEFUL FOR

Engineering students, hobbyist bridge builders, and project teams focused on structural design and assembly techniques for small-scale models.

I have a group project where we must build a small scale, cable-stayed bridge, with only one pylon (it's really an observation deck). The actual bridge is going to be a beam one.

I'm just wondering if anyone knows of some decent joints/fixtures that can be used to hold the wood pieces together? We're looking into glue but not so sure whether this might hold up? What about angle brackets?

Also we're kinda stuck as to how we should attach the wire (0.7mm in diameter) to the actual deck and pylon. We're definitely not going to use glue. We've looked into this small black rubbery ball shaped thing, but the opening is a bit too big for our wire and we can't find anything smaller. Anyone have any ideas for what material or fixture we could use?

Thanks.
