Quick question on Pedestrian Railing Anchoring

[bunker17]

Designing a pedestrian railing along a bridge, and getting down to anchoring the handrail. The handrail is 4.5' feet tall in 7' sections.

Under the AASHTO code do those anchors need to be designed for seismic design as well?

Thank you guys for any assistance you can provide!

I've never seen it done.

When designing anchorage to concrete in bridge design, I usually use ACI Appendix D which has provisions for seismic in D.3.3. If you are using rebar to anchor in, then you would use AASHTO 5.11 and there are no seismic provisions there.
