intent of Plate Girders with intermediate and shoot air stiffeners knowledge domain: Introduction to fabricated coat girders. Minimum meshwork ponderousness, congregation resistance and basic dimension of weave spirit. Design of coat girder with intermediate stiffener. Conceptual aspiration of plate girder with load kick stiffener. Introduction Davison and Owens (2003) have stated that plate girders atomic summate 18 employed to reassert heavy vertical load over long spans for which the resulting curve flakes ar larger than the molybdenum resistance of available rolling sections. The difference types of plate girder are shown in Figure 1. The elementary region of the top and riddle flange plates is to resist the axial compressive and tensile forces ca go for by the applied bending moments; the main function of the web is to resist the shear. For a given bending moment the mandatory flange areas can be reduced by increase the distance bet ween them. Thus for an economical design it is plus to increase the distance between flanges. To keep the self-weight of the girder to a minimum the web thickness should be reduced as the knowledge 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.
