2. Fiberglass reinforced plastic grating - Wikipedia

   en.wikipedia.org/wiki/Fiberglass_reinforced...

   Fiberglass reinforced plastic grating (also known as FRP grating, glass reinforced plastic grating or fiberglass grating) is a composite material manufactured by combining a matrix of resin and fiberglass. Fiberglass grating does not corrode like steel grating and is therefore used in corrosive environments to reduce maintenance costs.

3. Anti-slip grating - Wikipedia

   en.wikipedia.org/wiki/Anti-slip_grating

   Anti-slip steel grating is a type of bar grating. Steel bar grating is manufactured in a variety of methods. Welded bar grating consists of load bars electrically fuse welded to cross bars. Pressure-locked bar grating, or swaged grating, is where steel rods are forced through and locked in load bars. Riveted bar grating is where the load bars ...

4. Grating - Wikipedia

   en.wikipedia.org/wiki/Grating

   The grating profile is the function of the reflectance or transmittance perpendicular to the lines. This function is generally a square wave, in that every transition between lines is abrupt. A grating can be defined by six parameters: Spatial frequency is the number of cycles occupying a particular distance (e.g. 10 line pairs per millimeter ...

5. Open web steel joist - Wikipedia

   en.wikipedia.org/wiki/Open_web_steel_joist

   The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the structural frame i.e. beam and column. In order to accurately design an OWSJ, engineers consider the joist span between bearing points, joist spacing, slope, live loads , dead loads , collateral loads, seismic ...

6. Voided biaxial slab - Wikipedia

   en.wikipedia.org/wiki/Voided_biaxial_slab

   [citation needed] Another major benefit of the system is its reduction in slab weight compared with regular solid decks. Up to 50% of the slab volume may be removed in voids, resulting in less load on structural members. [1] This also allows increased weight and/or span, since the self-weight of the slab contributes less to the overall load.

7. Deck (bridge) - Wikipedia

   en.wikipedia.org/wiki/Deck_(bridge)

   A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.

8. Plate girder bridge - Wikipedia

   en.wikipedia.org/wiki/Plate_girder_bridge

   Generally, the depth of the girder is no less than 1 ⁄ 15 the span, and for a given load bearing capacity, a depth of around 1 ⁄ 12 the span minimizes the weight of the girder. Stresses on the flanges near the centre of the span are greater than near the end of the span, so the top and bottom flange plates are frequently reinforced in the ...

9. Span (engineering) - Wikipedia

   en.wikipedia.org/wiki/Span_(engineering)

   In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
