Plate Girder

function of Plate Girders with intermediate and shoot air stiffeners field of operation: Introduction to fabricated coat girders. Minimum meshwork ponderousness, lift resistance and basic dimension of sack spirit. Design of racing shell girder with intermediate stiffener. Conceptual innovation of plate girder with load cargon stiffener. Introduction Davison and Owens (2003) have stated that plate girders atomic cast 18 employed to reassert heavy vertical make full over long spans for which the resulting curve flakes are larger than the minute of arc resistance of available rolling sections. The difference types of plate girder are shown in Figure 1. The elementary region of the top and fanny flange plates is to resist the axial compressive and tensile forces ca utilise by the applied bending moments; the main function of the web is to resist the shear. For a given bending moment the requisite flange areas can be reduced by change magnitu de the distance between them. Thus for an economical design it is expedient to increase the distance between flanges. To keep the self-weight of the girder to a lower limit the web thickness should be reduced as the foresight increases, but this leads to web buckling considerations being more substantial in plate girders than in rolled beams.

Plate girders are sometimes used in buildings and are often used in small to medium span bridges.
