Loads produced by use and occupancy of a building or other structure, not including construction or environmental loads, such as wind load, snow load, ice load, rain load, seismic load, or dead load.
Structural loads or actions are forces, deformations, or accelerations applied to a structure or its components.
Loads cause stresses, deformations, and displacements in structures. Assessment of their effects is carried out by the methods of structural analysis. Excess load or overloading may cause structural failure, and hence such possibility should be either considered in the design or strictly controlled.
Mechanical structures, such as aircraft, satellites, rockets, space stations, ships, and submarines, have their own particular structural loads and actions.
Engineers often evaluate structural loads based upon published regulations, contracts, or specifications. Accepted technical standards are used for acceptance testing and inspection.
