| Term | Definition |
|---|---|
| Abutments | Supports at the end of and arch bridge that load and keep the ends from spreading out. |
| Abutments | Supports at the end of and arch bridge that load and keep the ends from spreading out. |
| Spandrels | Vertical support of an arch bridge used to distribute the weight of the roadway to the arch below. |
| Anchorages | Securing devices that are embedded in the solid rock 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 distance between two bridge supports |

| Buckling | What happens when the force of compression overcomes an objects ability to handle compression |
| Anchorages | Securing devices that are embedded in the solid rock or massive concrete blocks that spread cables over a large area to evenly distribute the load and prevent the cables from breaking free. |
| Snapping | What happens when tension overcomes an objects ability to handle tension |
| Span | The distance between two bridge supports |
| Dissipate | To spread force over a greater area so that no one spot has to bear the brunt of the concentrated force. |
| Compression | A force that acts to compress or shorten the thing it is acting on |
| Transfer | To move force over a greater area of weakness to an area of strength |
| Tension | A force that acts to expand or lengthen it is acting on |
| Spandrels | Vertical support of an arch bridge used to distribute the weight of the roadway to the arch below. |
| Truss | Supporting lattice work added to create very tall beams that add rigidity to an existing beam greatly increasing its ability to dissipate the compression and tension. |

| Torsion | A rotational or twisting force. |
| Span | The distance between two bridge supports |

| Deck-stiffening trusses | A supporting truss system beneath the bridge deck |
| Resonance | 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 |
| Dampeners | A technique used to interrupt the resonant waves |
