SPAN LOADING [6 records]

Record 1 2023-12-05

English

Subject field(s)
  • Road Traffic
CONT

The most severe loading for a long span bridge will occur with slow moving or stationary traffic because vehicles will be more closely spaced than in free flow. For a multi-lane bridge, lane loading will depend on how vehicles distribute themselves between lanes.

Subject field(s)
  • Structural Testing (Materials)
  • Structural Framework
CONT

The difference between [the two tensile strength tests] is the location of load application... In center-point loading..., the load is applied at the specimen midspan. In third-point loading, the load is applied at the third points along the test span. For the latter case, the middle third of the beam span is subjected to maximum bending moment, and thus maximum fiber stress.

  • Aircraft Airframe
OBS

... the Blended-Wing-Body(BWB) concept represents a potential revolution in subsonic transport.... In this study, 800 passenger BWB and conventional airplanes were compared for a 7000 nautical mile design range. ADP-class engines were used with technology levels keyed for a 2015 entry into service(EIS). In every measure, the BWB was found to be superior to the conventional configuration. Key findings for the BWB include : TOGW 15% lower[;] OEW 12% lower [;] Fuel-Burn 28% lower [;] Thrust 27% lower [;] L/D 21% higher [;] DOC 13% lower [. ] The BWB advantage results from a double-deck cabin that extends spanwise as well as lengthwise providing structural and aerodynamic overlap with the wing. This reduces the total wetted area of the airplane and the deep stiff centerbody provides efficient structural wingspan. Relaxed static stability allows optimal span loading, and a trailing-edge high-lift system is not required. Further synergy may be realized through buried engines that ingest the centerbody's boundary layer and thus reduce the effective ram drag.

DEF

A loose term indicating a beam with a depth/span ratio such that the maximum loading it will carry depends on shear strength or lateral stability rather than bending strength, or such that its deflection is materially affected by the sheer stresses in it.
