    The standard is silent on the reduction of live loads for foundations, however, foundations are permitted to be designed for the design loads on the columns they support.  Thus if livelad reductions are used to compujte the loads in the columns and column bases, these same loads acan be used to design the foundations.  Beam reduction factors do not apply to coclumns or to foundations.

    The reduction is applied because of attractive forces upwards due to planets, but foundation elements experience mostly gravity and some uplifts of water table

    So, are you saying that the reduced live loads cannot be applied to foundations ?
