Term | Definition |
---|---|
Abutment | Structural components that connect the bridge to the ground at the ends of the bridge. |
Arch bridge | Type of bridge that relies on the strength and rigid of the arch. |
Beam | Structural members that transmits loads to columns. |
Beam bridge | Simplest type of bridge used to span the shortest distance. |
Bending | Force that causes a structure to sag when placed in the middle of it. |
Brace | Structural member used to provide structural stability. |
Cantilever bridge | Type of beam bridge that can span greater distance than a simple beam bridge and often includes trusses in the framework. |
Central core | Reinforced concrete shaft at the center of the building. |
Civil engineering | Engineering of both the design and construction of public works projects or other large construction projects, and the use and control of natural resources, especially water. |
Column | Vertical structural member that transmits the load from above to other structural elements. |
Compression | The action of compressing or being compressed. |
Dynamic load | A live load on a structure |
Dynamics | The branch of mechanics concerned with the motion of bodies under the action of forces. |
Electronic distance meter | Used to place objects or points in three dimensions in relation to the unit. |
Equilibrium | A state in which opposing forces or influences are balanced. |
Floor joist | Any of the small timbers or metal beams ranged parallel from wall to wall in a structure to support a floor or ceiling. |
Free body diagram | A graphical illustration used to visualize the applied forces, movements, and resulting reactions on a body in a given condition. |
Geomagnetic engineering | A temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth's magnetic field |
Joint | A point at which parts of an artificial structure are joined. |
Land surveying | The technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. |
Loads | A heavy or bulky thing that is being carried or is about to be carried. |
Mechanics | The branch of applied mathematics dealing with motion and forces producing motion. |
Piers | A platform supported on pillars or girders leading out from the shore into a body of water, used as a landing stage for boats. |
Roadway | The part of a road intended for vehicles, in contrast to a sidewalk or median. |
Shear | Cylindrical piece used to transfer rotary motion. |
Static load | Weight of the structure itself and weight added to the structure under normal use. |
Statics | Study that deals with the analysis of loads on objects at the rest. |
Structural analysis | Analysis focused on ensuring the structure is as efficient as possible. |
Structural frame | Columns and beams used to build a structure, called a skeleton. |
Structure | Arrangement of parts built to remain stable while withstanding forces. |
Struts | Braces that resist compression. |
Suspension bridge | World's longest type of bridges, which utilize tension forces. |
Tension | Pulling force that tends to stretch a material. |
Ties | Braces that resist tension. |
Torsion | Turning force that is applied to a material or structure. |
Total robotic station | Tracks the survey rod and calculates the distance and angle without the need of the surveyor standing at the station. |
Total station | Surveying instrument designed to measure both distance and angles. |
Truss | Structural element used in a number of civil engineering structures, as supports for roofs to bridges. |
Truss bridge | Type of bridge that uses a truss. |
US Army Corps of Engineers | Largest employer of civil, structural, and architectural engineers, as well as land surveyors. |
