Hands On Bridge Building
This activity will allow the students to browse and search for information required to complete their project. The bridge will be designed and built by the students out of inexpensive materials such as spaghetti, tape and glue. Other materials, such as straws or popsicle sticks, may be substituted as the situation or budget dictates. It will require the students to do a cost analysis of their project and to conceptualize how their completed project will look before having built it. The spaghetti bridge can be a fun and challenging activity.

Lesson Plan : To Build A Bridge
(middle/high school science) Students explore the different facets that must be considered to design and construct a bridge. They start with a look at materials vs. design and then end up with a brief look at some of the ethical concerns of engineering projects.

Balsa Structure Tips
Start simple! Draw out your designs first thinking about what will happen when you place weight on the top of the structure. When building, take the time to do things right, don't try to rush, be precise, don't be sloppy with the glue bottle!

Tom's Tips for Structures Competitions
My advice for building winning structures starts with commitment. Your dedication and attention to detail is the winning combination. My list of tips will help you succeed but only if you are dedicated to the project. Be sure you understand the event rules before designing your prototype.

Bridge Building
Bridges must be built strong enough to safely support their own weight as well as the weight of the people and vehicles that pass over it. The bridge must also withstand natural occurrences that include weathering, earthquakes, strong winds, and freezing and thawing.

Bridge Building Home Page
The construction and testing of model bridges promotes the study and application of fundamental principles physics and also helps high school students develop "hands on" skills through bridge construction. By participating in the Bridge Building Competition students get a flavor of what it is to be an Engineer, designing structures to a set of specifications and then seeing them perform their function. They are also provided with an academically-oriented extracurricular activity which is recognized school-wide.

Spaghetti Bridge Building
The Spaghetti Bridge Building Webquest is designed for a team of four students to design and build their own spaghetti bridge. The team researches bridge designs, researches insurance, chooses occupations, and tracks spending. At the conclusion of the project the bridge is stress-tested to determine its strength.

West Point Bridge Design Contest
The purpose of the contest is to provide middle school and high school students with a realistic, engaging introduction to engineering. We provide this contest as a service to education--and as a tribute to the Academy's two hundred years of service to the United States of America.
The West Point Bridge Designer 2004 will introduce you to engineering through an authentic, hands-on design experience. This software provides you with the tools to model, test, and optimize a steel highway bridge, based on realistic specifications, constraints, and performance criteria.

The Tacoma Bridge Failure
The Tacoma Narrows Bridge in Washington state, with its 1.9 km span, was one of the largest suspended bridges built at the time.
It opened to traffic on July 1, 1940 and was quickly nicknamed "Galloping Gertie" because of its rolling and undulating behavior: on windy days, motorists driving on it felt like being on a huge wave and would see the cars ahead disappear from view!

The Tacoma Narrows Bridge - The original Tacoma Narrow Bridge, at all stages of its short life, was very active in the wind. Its nickname of Galloping Gertie was earned from its vertical motions in even very modest winds. Its collapse on November 7, 1940 attracted wide attention at the time and ever since, due in part to its capture on film.
The Koror-Babeldaob Bridge - The K-B Bridge was a 790 ft span concrete box girder bridge, built using the cantilever method in the late 1970s. It collapsed suddenly one evening in September 1996, after it had stood for almost 20 years. These pictures were scanned from postcards available at the Palau international airport.
The Tay Bridge Disaster - At approximately 7:15 p.m.on the stormy night of 28 December 1879, the central navigation spans of the Tay bridge collapsed into the Firth of Tay at Dundee, taking with them a train, 6 carriages and 75 souls to their fate.

Tacoma Narrows Bridge
Throughout the early morning hours of Thursday, November 7, 1940, the center span had been undulating three to five feet in winds of 35 to 46 miles per hour. Alarmed by this constant motion, highway officials and state police closed the bridge at 10:00 A.M. Shortly thereafter the character of the motion dramatically changed from a rhythmic rising and falling to a two-wave twisting motion. The twisting motion grew stronger with each twist; span movement had gone from 5 foot to 28 foot undulations. This twisting motion caused the roadbed to tilt 45 degrees from horizontal one way and then 45 degrees from horizontal the other way.

The original, 5,939-foot-long Tacoma Narrows Bridge, popularly known as "Galloping Gertie," opened to traffic on July 1, 1940 after two years of construction, linking Tacoma and Gig Harbor.

Pontifex
http://www.chroniclogic.com/pfx.html
Pontifex is the official sequel to a freeware game in which you design and test bridges. Pontifex uses a complex physics engine called the Immortal Engine which allows for many different types of bridges to be built. Once the design is completed you can test your bridge by sending a train across and watch as the train either passes over safely or plummets into the river below. The 3D engine lets you view your bridge from any angle including a first-person train view. Many different types of levels are included, from simple to complex, and a level editor lets you make your own levels to trade with other people.
