    No, we would not. The beams have a loading that they must adequately support. They have a span that is dictated by the column spacing. There are moment, shear and deflection requirements that must be met.

    You cannot just throw in supports (i.e., columns, bracing) everywhere to reduce the span until it works, otherwise you impact the usability of the building space and drive up the cost of construction.

    Reducing the beam to beam spacing means you are increasing the number of structural elements and therefore cost, and probably also using the material inefficiently. The expensive part of a beam is the connection, and you typically want to reduce the number of connections and crane lifts as much as possible.
