| Brittle | —A characteristic of a material that fails by rupturing suddenly and without warning, when loaded in tension. |
| Concrete | —A structural material made by mixing cement, sand gravel and water |
| Deck | —The flat surface that forms the floor of a bridge and supports the roadway. |
| Ductility | —The capacity of a material to undergo very large plastic deformation before rupturing |
| Deformation | A change in the size or shape of a structuralmember that occurs when the member is loaded. |
| Abutment | ——A concrete wall that supports the end of a bridge and holds back the soild that is filled in behind it. |
| Force | —A push or a pull applied to an object. A force always has both magnitude and direction. |
| Equilibrium | —The condition that occurs when the total force acting on an object is zero. |
| Support | —A point at which a structure is physically in contact with its surroundings. |
| Unstable | —A structural configuration that cannot carry load because one or more members can move or rotate without restraint. |
| Pier | —A foundation element that supports a bridge in the middle of the gap |
| Tensile Strength | —The maximum tension force a member can carry before it fails. |
| Stable | —A rigid structural configuration in which no member or members can move or rotate freely |
| Truss | —A structure composed of members connected together to form a rigid framework. |
| Joint | —The point at which two or more members are joined together in a structure. |
