TermDefinition
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.
