-----Original Message-----No, they are supported by magic. Okay, not really magic, but a careful random combination of gwb ceiling tension, unanticipated load paths through non-loadbearing walls, and hoop stresses in the roof diaphragm. The IBC, if I remember, is no more helpful than what you've probably found in the UBC.
