Baseplate Design - Poles

Hello,

I would like to know how to design a baseplate for a steel floodlighting pole. In particular, a baseplate that goes through the pole and is fillet welded top and bottom. How are the stresses transferred through the baseplate to the pole ? What effect does the hole in the baseplate have ?
References to any articles or text books would be greatly appreciated.
Regards.

For the design of circumferemtial fillet welds you can refer to

Formulas for Stress, Strain and Structural Matrices
Pilkey
Wiley Interscience

I ported the procedure to Mathcad 2000 Pro as well, freely downloadable from the Collaboratory site.

A filled weld has specific formulations for any layout, sometimes simplified to 1 or 2 formulations. Of course if you may need gusset plates to have a less thick baseplate.
