steel framed building on piles need lateral resisting system
(OP)
We have a steel framed building on piles which has no lateral resisting system. we will add cross brace, but it will transfer the load to piles. we are thinking of add grade beams between the two pile caps, or install additional battered piles.
If we use grade beam, the piles will take moments, I don't know whether piles can take moments since they are supposed to take only axial loads. each pile cap has 3 to 4 piles.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

to kootk: this is a parking garage, so no walls around, stair walls just separated cmu walls.
Actually the 3 supported level garage was laterally resisted by column moment connection, but we need to extend one level above, and we find all columns are shy, only good for gravity load. so we will ignore the moment connections and try to build brace system to take laterally load. so only braced columns need reinforcement. But lateral load on footing is a problem.

The piles themselves should be able to take moment then. You'd need a geotechnical engineer to figure out if the surrounding soil can however. No uplift on the pile cap to pile connection to worry about?
The grade beam and battered pile option is calling to me. I couldn't resist taking a swing at it as it could be quite elegant. No doubt there are complications that I'm not aware of.

I only have 12" from top of pilecap to finish grade. I am thinking of putting a steel beam between the two columns at bottom to sub the concrete grade beam. But maybe I still need concrete encasement.

The idea of pile group is much better, you are a structural genius.
