Design a welded plate girder for simply supported bridge deck bear with a clear span of 20m, subjected to the following: Dead load = 18 kN/m,Impesed load = 8 kN/m, Two moving loads = 140 kN each spaced 2.5 m apart.Assume that top compression flange of the plate girder is restrained laterally and preventedfrom rotating. Use Ex- 250 MPa. Design as an unstiffened plate girder with thin webs.
A. A simply supported girder spans 12 m. It carries two (2) beams, each at 4.5 m. from the supports. The concentrated load from each beam is 75 KN. Don't neglect the weight of beam W410x100 Properties Beam Section W410 mm x 100 kg/m Ix-397 x 106 mm, ly=49 x 106 mmª, tf = 21 mm, tw=15mm, Modulus of elasticity E = 200 GPa, Consider bending about the x-axis.

A W36x210 can be used for Transfer Girder ‘A’ as shown in the elevation next page.Assume the LRFD loads on the ‘Transfer Girder’ are as follows:Pu= 200 kips from the column above. Assume also that the loads from self-weight of thewu = 2.0 kip/ft (girder self weight and beams framing into this transfer girder are equivalentto a uniformly distributed load). These loads are shown in the last figure.a) Check whether the W36x210 ‘Transfer Girder’ is adequate for bending and shear.Assume the unbraced length Lb =20 ft.b) Suppose that service loads, w and P, are both 50% dead load and 50% live load. Does theW36x210 satisfy a service live load deflection limit of L/480?
