Beam
A structural member, usually horizontal, with a main function to carry loads cross-ways to its longitudinal axis. These loads usually result in bending of the beam member. Examples of beams are simple, continuous, and cantilever.
Beam-Column
This is a structural member whose main function is to carry loads both parallel and transverse to the longitudinal axis.
Cantilever
Cantilever refers to the part of a member that extends freely over a beam, which is not supported at its end.
Collateral Load
Collateral load is additional dead loads (not the weight of people and not the weight of the building itself), such as plumbing, duct work, ceilings, and other components of the structure.
Column
A column is a main vertical member that carries axial loads from the main roof beams or girders to the foundation parallel to its longitudinal axis.
Continuity
Continuity is the term given to a structural system describing the transfer of loads and stresses from member to member as if there were no connections.
Damping
Damping is the rate of decay of amplitude for floor vibrations.
Dead Load
Dead load describes the loads from the weight of the permanent components of the structure.
Deflection
Deflection is the displacement of a structural member or system under a load.
Dynamic Load
This type of load varies over time.
Footing
A footing is a slab of concrete under a column, wall, or other structural to transfer the loads of the member into the surrounding soil.
Foundation
A foundation supports a building or structure.
Load
An outside force that affects the structure or its members.
Torsion Loads
A load that causes a member to twist about its longitudinal axis. A couple or moment in a plane perpendicular to the axis produces simple torsion.
Compression The force that makes the bridges' ends want to come together.
Tension The force that tries to separate the bridges' ends.
