Term | Definition |
---|---|
Abutments | Supports at the end of an bridge that carry the load and keep the ends from spreading out. |
Spandrels | Vertical support of an arch bridge used to distribute the weight of the rood way to the arch below. |
Anchorages | Securing devices that are embedded in the solid or massive concrete blocks that spread cables over a large area to evenly distribute the load and prevent the cables from breaking free. |
Span | The distant between two bridge support. |
Compression | A forces that acts to compress or shorten the thing it is acting on. |
Buckling | What happens when the force of compression overcomes an object's ability to handle compression. |
Snapping | What happens when tension overcomes an object's ability to handle tension. |
Dissipate | To spread force over a greater area so that no one spot has to bear the brunt of the concentrated force. |
Transfer | To move force from an area of weakness to an area of strength. |
Truss | Supporting lattice work added to create very tall beams that rigidity to an existing beam greatly increasing its ability to dissipate the compression and tension. |
Torsion | A rotational or twisting force. |
Deck-stiffening trusses | A supporting truss system beneath the bridge deck. |
Response | A fatal force to a bridge that is a vibration caused by an extended force that is in harmony with the natural vibration of the original thing. Resonance vibrations travel through a bridge in waves. |
Dampeners | A technique used to interrupt the resonant waves. |
