Is it necessary to do strength design for concrete footings assigned t
Is it necessary to do strength design for concrete footings assigned t
(OP)
Apart from the settlement and overturning requirements (12.13.3 and 12.13.4 of ASCE7-5) for footings as parts of structures assigned to seismic design category B, are their other requirements for concrete isolated or combined footings in terms of strength and detailing?
Thanks
Thanks

Uplift - yes, as a part of stability.
ACI 318 for bending and shear strength - do you mean use seismic load combo to size reinforcing bars? But in chapter 21 of ACI 318-08, only foundations of structures to SDC D, E or F are required to resist earthquake induced forces, see 21.12.1.1.
