in which of the following situations would double floor joists not be needed?\no under floor openings for stairs\no under heavy objects like whirlpool tubs\no under load - bearing interior walls running parallel to the joists\no under load - bearing interior walls running perpendicular to the joists

Answer

Brief Explanations:

Double - floor joists are used to provide extra support. Floor openings for stairs, heavy objects like whirlpool tubs, and load - bearing interior walls running parallel to joists require additional support. When load - bearing interior walls run perpendicular to the joists, the joists can distribute the load more effectively without the need for double joists in many cases.

Answer:

under load - bearing interior walls running perpendicular to the joists
