Truss Bridge | Beam bridges that have one or more triangles. |
Suspension Bridge | A type of bridge where the deck is suspended by hangers from continuous steel cables. |
Critical Load | The amount of force a structure can hold before failing. |
Dead Load | Dead loads are permanent loads; they do not change. The weight of a building is a dead load. |
Structural Failure | A condition that occurs when structures are not able to support the loads placed upon them and they collapse. |
Compression | The tendency to condense or squash a material. |
Tension | The tendency for material to stretch, or to be pulled apart. |
Shear | The tendency of a material to be divided by two opposing forces. |
Thrust Lines | Imaginary lines of force caused by loads, transmitted through the structue to the ground. |
Cantilever | When ends of a beam are allowed to overhang the support walls by a short distance. |
Stress | Measured in newtons, it's the intensity of the forces trying to push or pull a solid material apart. |
Bridge Failure | Shear near supports, crumbling piers, stretching cables are examples. |
Three basic types of bridges. | Beam, Arch, and Suspension |
Examples of live loads. | People, furniture, snow on a roof, wind |
Interstate Highway System | In 1950's created a boom in bridge building. |
Beam Bridge | Lighter and cheaper than an arch bridge. |
depth | The most important factor in determining the strength of a beam or truss bridge. |
