Another notable bridge is the Esker Overhead, shown in Fig. use prestressed concrete girders with with a PCI-type cross-section (Precast Concrete Type I). The many types of loads discussed previously can occur simultaneously on a structure, but it is very unlikely that the maximum of all these loads will occur at the same time. Cross section of T-Girder with cast in situ deck b. I-Girder with cast in situ deck c. Box girder with cast in situ deck Fig2.1. A girt is a vertically aligned girder placed to resist shear loads. The outer girder has an overhang of 1.765 m. from the centre line of girder and centre to centre distance of girders is 2.45 m. Therefore, the outer girder is also a T-beam.

The comparative results of computer analysis are discussed in Chapter 7 to further clarify the advantages and distadvantages. A girder is simply a type of support beam. A concrete spall outside the anchorage zone is also not significant. It is the main horizontal support of a structure or the large beam that supports smaller beams. 2. Author Gordon Luckett. It is a type of pre stressing in which steel wires (tendons) are stretched before the placement of concrete. The loads applied to a spandrel joist girder come from one side, while on an inside bay the The two most common types of modern steel girder bridges are plate and box. 251-442-6373 Info@thehushproject.org | P.O. Plate girders -Dr. Seshu Adluri Slender webs buckle easily due to shear or bending Use reduced effective c/s or Use reduced capacity Plate Girders. A finite element model of the girder cross-section for three types of MoDOT girders (Types II, III and VI) was developed to analyze distribution of residual stress due to early-age differential thermal loading caused by steam curing and hydration. Center to center span of main girder =24m, provided at a spacing of 1.3m, 0.6kN per meter stock rails and 0.4kN per meter guard rails are provided, weight of fastening may be taken as 0.12kN per meter, The sleepers are placed at 400mm from center to center and size 2mx 250mmx 250mm.unit weight of … this type of bridge is shown in Fig. The girder spacing of 2 to 3 m.
