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:
- Flexural Strength
- Shear Strength
- Bearing Stiffeners
