Below is information concerning the types of bridges and information about our bridge building project. In modern girder bridges, steel I-beams are used, but they are subject to twisting and are not good for bridges with any curve to them. This modern bridge type uses box girders made not of steel plates but of concrete reinforced with steel bars. Suspension bridges involve a continuous girder hung from cables supported by towers erected on piers. Similar to a cable-stayed bridge except there is one main cable that runs between the towers with hanger cables below it.
The girder and roadbed are not resting on the piers as with other bridge types, but is hanging from the hanger cables! A typical cable stayed bridge is a continuous girder with one or more towers erected above piers in the middle of the span.
First, you must have drafted an accurate and well thought out plan before you can start building your bridge. Drawing is extraordinarily well done with dimensions, title, scale, and details and it accurately depicts the actual bridge. Drawing is well done with dimensions, title, scale, and details and it accurately depicts the actual bridge. All students will be using equal amounts of materials to build a bridge in class in teams consisting of two students.

Balsa wood is unique from all early Its properties make how do you make a balsa wood bridge it valuable to bridge builders wood carvers surfers and many others. After reading the information about bridges go to: the Build a Bridge Game to find out if you understand the different purposes for different bridges. The arch transmits the load from the bridge deck to the abutments on both sides of the span and thus to the ground below. They are a very old bridge form, although, in their modern incarnation, they are widely used where very long spans are needed. A truss bridge uses a series of triangles in some sort of superstructure to transfer the load from the deck to the piers.
Here, the diagonal members all slant toward the closest bridge end, so they are subject to compressive forces. Constructing amp wide-eyed bridge using balsa woodwind can be angstrom fun and educational experience. Parents and teachers interested in helping young students with the construction of a good balsa wood bridge, can be certain that this affordable software will not only guide the students in building bridges that satisfy all the requirements, it will also induce creativity and confidence to complete every task in an efficient way. After viewing the content of this software, we believe that every student will have the knowledge, the confidence, and the determination to design and build a good balsa wood bridge that meets all the requirements. They will see the benefits of making a blueprint on graph paper or in the computer, before building the actual bridge. Bridge building is a popular competitive activity in middle and high school classrooms that challenges students to design and construct a wooden bridge, calculate its efficiency, then select the best design. In addition to classroom competition, there are numerous state and nationwide bridge building competitions held annually that offer recognition and awards.

The introduction of steel wire cables in the 1830s greatly extended the potential of suspension bridges. Since the elements of a truss are subject only to tension (stretching) or compression (pushing) forces and cannot handle bending forces, truss bridges are typically best used for straight alignments. Students should also use this opportunity to research common problems associated with bridges. Students have the opportunity of viewing a wide variety of standard and original bridge designs.


One of the tutorials incorporated in the software shows in detail the complete step-by-step planning and construction of the bridge shown in the last picture. The tutorials incorporated in the software use more than 200 pictures and graphics to explain numerous bridge construction principles, including how to cut and join the wood sticks for maximum strength. This project requires Illustrated step away step guide on how to design and build exemplary bridges. Many modern beam bridges are composed of beam girders (typically I-beams or box girders) supported on piers. Short modern arch bridges may use wood or concrete, while longer arch spans are built of steel.
At both ends of the bridge, large anchors are placed (usually underground) to hold the ends of the main cables. A truss bridge can support heavy weights and span long distances, but it requires a fair amount of vertical room to accommodate the truss structure. Patented by Caleb and Thomas Pratt in 1844, this was among the most common American bridge types for the ensuing decades and was built in both wood and metal. Students are also taught how to plan and design on graph paper the construction of their own bridges.
If you are interested in purchasing this educational product (Balsa Wood Bridges - Product # BRID1), please send your check or money order for $125.00 to the address shown below. The main cables are stretched from anchor to anchor over the tops of the towers, passing over a saddle which allows the cable to slide as loads move on the bridge.
Though only a few cables are strong enough to support the entire bridge, their flexibility makes them weak to a force we rarely consider: the wind.
One of the positive aspects of this software is that it gives students ideas on bridge design, in addition to basic principles they have to keep in mind in order to construct a strong bridge. Besides drawing the canonical intent on paper as well sop up indium close to of the straight off atomic number 53 don't want you to start squeezing every stick of Balsa Mrs. For longer span cable-stayed bridges, careful studies must be made to guarantee the stability of the cables and the bridge in the wind. Once complete failure occurs or any part of the bridge touches the river, the bucket will be weighed to find the overall weight supported by the bridge. In that way, students can observe how every side of the bridge was put together, including its front, top, side, and bottom. Since the strength of a beam bridge depends largely on the close spacing of piers, this bridge type is generally ill-suited to long spans. While other bridge types are supported by piers or abutments, here the girder and bridge deck hang suspended from the main cables.
Since the abutments transfer both horizontal and vertical forces from the bridge deck, arch bridges can only be used where the ground or foundation is solid and stable.
Due to the flexibility of the cables, long suspension bridges are prone to vibrate in high winds, much like the string of a guitar or violin. Construction of an arch bridge is difficult, since the structure is unstable until the two sides of the arch are joined.
