Hi SUSheikh,
You are welcome.
In Hu design, we use factor load, not SLS load.
When consider Hu, we have to explicitly consider Hu per pile or total Hu per footing. Your approach is correct. I'd used this approach to design piles of bridge abutment for 20m steel I girder span to resist lateral seismic force in Solomon Island (4 years ago) and 2000ton anchor bed for pretensioned casting yard 15 years ago. It's still there and working well until now.
