    The plate girders is a type of beam built from plates of steel that are either bolted or welded together.
    The plate girder are typically I-beams made up from separate structural steel plates which are welded or bolted or riveted together to form the deep vertical web with a pair of angles each edge to act as compression and tension flanges.
    Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic.
    Types of Plate Girder:
    1.Deck type plate girder
    2.Half through plate girder
    3.Multi-span plate girder
    Bridge construction in roadways, highways, pedestrian etc
    1. Heavy loading capacity.
    2. Great stability and long fatigue life.
    3. Speedy erection.
    Retaining Wall:
    Retaining walls are relatively rigid walls used for supporting the soil mass laterally so that the soil can be retained at different levels on the two sides.
    A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil.,-Lisburn,-Antrim,-Limestone-Blend-5.jpg
    3.Sheet piling
    4.Board pile
    Difference between Cantilever and Counter
    Cantilever Retaining wall Counter fort Retaining wall
    1.Stem/toe/heel bend like cantilever slab Stem/Heel bend like continuous slab
    2.It does not require any support Counter fort are provided as support
    3.Economical below 6-7 m height Economical above 7 m height
    4.Uniformity of stress is not maintained Uniformity of stress is maintained
    1.Preventing soil erosion
    3.Visual Interest
    1.culvert walls
    2.Flood wall
    3.Tunnel portals and approaches
    Water tank:
    A water tank is a container for storing water.
    1.Chemical contact tank
    2.Ground water tank
    3.Elevated water tank
