    1. Yes, you can do that. These are called hung columns. These are columns, having no foundation/ footing, rest over beams, or slabs. These are also termed as hanging columns/ floating column.
    2. They can not transfer load directly to the foundation or footing. Load from these columns is the point load on the beam over which it rests.These beams are generally deep beam need high percentage of reinforcement, also termed as transfer beam. Load is transferred through the transfer beam to the supporting columns, ultimately to the foundation.
    3. These columns are designed to take vertical load , considering it a compression member.
    4. These are abundantly provided to get more space in the ground floor to keep provisions for parking, conference hall, architectural requirement , banquet hall in hotels, commercial building etc.These are also provided in intermediate floor for the similar purpose.
    5. These columns are designed for vertical load only. In earthquake prone areas these may prove unsafe. If at all provided, they will not take lateral forces, all seismic forces shall be taken by the main columns supporting the transfer beam.
    6. Reinforcement detailing is an important issue in the design of column- beam junction.
