The method you use to test your model bridge will make or break it. Okay, most of the time the bridge breaks no matter what. How much weight your bridge holds before collapsing is partly determined by how you test the bridge. Whether you have a popsicle stick bridge, balsa bridge, toothpick bridge or other type of model bridge, these testing tips will give you a jump start and help you make an informed decision on how to test your bridge.
Building a model bridge is one of the most rewarding hobbies I have done in my entire life . I have learned a ton about working with wood and tools. I have also learned the basics in bridge engineering, and have a greater appreciation for real bridges. Model bridge building has also given me a originative outlet that I can share with others. Not only does it give me something fun to do, I can show off my creations and attest to their abilities.
This is the absolute best video I have seen about building model bridges. Roy Coleman, the founder of the International Bridge Building Contest, gives a very informative presentation in this video. The presentation is over an hour long. He shows how to build a bridge from scratch. He is gearing his video towards the…
This kit is actually one of my first introductions to building model bridges. My mother bought this for me one year, thinking that I might like to build a model bridge kit. This bridge building kit from Amazon actually has three different bridges. It comes with all the supplies you need to build a suspension bridge, a truss bridge, and an arch bridge. All of these combined make this kit an excellent gift idea, or something you can build just for fun
This ebook, 5 Steps to Building a Model Bridge, answers the most common questions people have about building bridges. In the ebook I outline the steps of building a model bridge, and then walk people through the actual construction of a bridge. The ebook contains many photos and illustrations, as well as 25 bonus tips.
I found pictures of some old trusses I built for Science Olympiad bridges. Most of these were built in the 2003-2004 school year. I thought I would post them to give examples of how these trusses could be used in model bridges
Are you interested in building bridges for your model railway set? This book is a great resource, and is cheap from Amazon. This guide is rated 5 stars and will help you create bridges and tunnels for your layout. It will teach you how to build prototypes of many real life train bridges. What is neat about this book is that it gives you the history of the bridge you will be building. It is always fun to know the story behind the structure you choose to add to your set
It’s taken me just under 48 hours to get this far. Although i wouldn’t say its completely finished.. it’s a good as. I might just polish it off with a lick of paint and other aesthetically pleasing type things. As you can see, I’ve modeled it on the Pratt Truss. Although, I didn’t do any “real” plans, just rough drawings
Garrett- Jobs well done – interesting site and information! We built a 1/8″ scale model bridge just like the bridges we build for production. We successfully loaded it with 345 pounds with the weight being distributed all the way across the middle. Do you know of a formula where we can figure out that weight capacity for our full scale bridge? We have contacted 3 different engineers in our area who don’t have access to such information. Thank you for […]
No Longer Available I am always on the look out for good software to help design model bridges. My latest find, Dr. Software, is a series of programs that allow you to customize a design, put a load on it, and see what happens. Dr. Truss comes in 2D and 3D options. You can also get Dr. Beam, which allows you to word with a beam and not a truss. The pictures in this post are from Dr. Truss 2D. […]
Came across this today. Here is a scale model of the Brooklyn Bridge. Brooklyn Bridge (Sorry, but the website is no longer available). The website has some other interesting info about bridges, including screenshots of designs for the West Point Bridge Design contest. BTW, that contest starts today. If you haven’t checked it out, do so now. Manilla File Folder Bridge It is free, and lots of fun to play around with.
I have always wanted to build a model suspension bridge, and finally I have finished one. This is a popsicle stick suspension bridge. I created it from scratch, coming up with the design on my own. After testing it to failure I learned quite a bit about how suspension bridges react to loads. This model suspension bridge uses popsicle sticks as the main building material. The decking is cardboard, and the “cables” are 550 parachute cord (military surplus)
