The document defines and describes 10 different types of structures: beam bridge, truss bridge, suspension bridge, arch bridge, shell structure, frame structure, solid structure, and two additional descriptions of beam and arch bridges. A beam bridge uses a horizontal beam supported at both ends to support weight. A truss bridge uses a lightweight truss structure for stability. A suspension bridge hangs between two ends for support. An arch bridge can withstand heavy loads. A shell structure has a solid outer surface and hollow inner area. A frame structure uses a skeleton frame for support rather than walls. A solid structure is made of solid, strong material.

1. 10 different structures with definitions!!! Structures Woohooo!!!!!!!! YAY!!!!! WOOT WOOT !!!!!

2. Beam Bridge A beam bridge is a flat surfaced bridge A beam bridge needs to be stiff. It needs to resist twisting and bending under load. In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers.

3. Truss Bridge Truss Bridges are light weight structures made of trusses along it, too make it stable and secure

4. Suspension Bridge A suspension bridge is a structure that hangs between two ends to hold it up!!!

5. Arch Bridge An arch bridge’s structure is built to with stand heavy loads

6. Shell Structure Shell Structure is a structure with a solid outer surface *which may be rounded or flat in shape*with a hollow inner area For Example a Styrofoam cup

7. Frame Structure Structure supported mainly by a skeleton, or frame, of wood, steel, or reinforced concrete rather than by load-bearing walls.

8. Solid Structure A solid structure is made of a solid piece *or solid pieces * of strong material such as cement

9. Another Beam Bridge :P:P Beam bridges are the simplest kind of bridge today. They are a direct descendant of the log bridges, now more commonly made from shallow steel, I beams, or concrete!

10. Another Arch Bridge The advantages of the segmental arch bridge were that it allowed great amounts of flood water to pass under it, which would prevent the bridge from being swept away during floods and the bridge itself could be more lightweight
