Design Assumptions and Limitations

Design Assumptions and Limitations Use this Index with Index 521 - 422, 521 - 423, 521 - 427, 521 - 428, 521 - 820, 515 - 0 21, 521 - 51 0 as appropriate. Anchor Bolts were designed for Design Wind, Bridge Deck Height (above MLW), Luminaire Mounting Height, and Luminaire Arm Lengths of Standard Index 715 - 0 02 Light Poles with a maximum 40 foot luminaire mounting height . Design of the additional bridge deck reinforcement is based on the minimum transverse top deck reinforcing required by the SDG .

The nominal load capacities given should be greater than the computed light pole loads calculated using the LRFD LTS Extreme Event I limit state. Axial Dead Load = 1.56 kip Wind Load Moment about Bridge Transverse Axis = 40.6 kip - ft Wind Load Moment about Bridge Longitudinal Axis = 28.3 kip - ft Dead Load Moment about Bridge Longitudinal Axis = 1.69 kip - ft Torsion about Pole Axis = 3.56 kip - ft Maximum Shear = 1.38 kip Locate pedestals near a substructure support to minimize vibration of the light poles due to traffic live loads. Locate the centerlines of pedestals a minimum 3' - 10" away from centerlines of open joints in railings and ends of railings.

Payment

Payment No separate payment is made for Light Pole Pedestals. See Payment Note on the Standard Plan .

What your plans must show

Plan Content Requirements for this index — the SPI's checklist for designers.

• In the Structures Plans: Show Light Pole Pedestals on Plan and Elevation, Superstructure and Approach Slab Supplemental Detail sheets. Use stations or longitudinal dimensions along bridge to define pedestal locations. Include anchor bolt diameters.
