Example 1 - How to Analyze a Steel Plate Girder Using the AISC Steel Design Code

Check the adequacy of the plate girder shown below given the following information using LRFD approach:

Uniform Service Dead Load (including self-weight) - 0.5 kip/ft

Uniform Service Live Load - 1.5 kip/ft

Concentrated Service Dead Load - 5 kips

Concentrated Service Live Load - 15 kips

Compression flange laterally supported and restrained against rotation at supports and at points of concentrated loading

Bearing stiffeners located at supports and at points of concentrated loading

Bearing stiffeners clipped 1" at inside edge on top an bottom to clear flange to web welds

No intermediate stiffeners

A36 steel material is used for all components

Assume all welds are adequate

Check:

  1. Flexural Strength
  2. Shear Strength
  3. Bearing Stiffeners
