When rafters are placed opposite each other and ceiling joists are supported on a bearing wall, how are the joists installed?

  1. Be placed on the same side of the joists, butted together at the bearing wall and toe-nailed to the bearing wall.

  2. Set on opposite sides of the rafters, lapped over the bearing wall and nailed together.

  3. Set on opposite sides of the rafters, lapped over the bearing wall, spaced with a block and nailed together.

  4. Set on the same side of the rafters, lapped over the bearing wall and nailed together.

The correct answer is: Set on opposite sides of the rafters, lapped over the bearing wall, spaced with a block and nailed together.

When rafters are placed opposite each other and ceiling joists are supported on a bearing wall, the joists are typically installed by setting them on opposite sides of the rafters and lapping them over the bearing wall. They are then spaced with a block and nailed together to provide support. Option A is incorrect because the joists are not typically placed on the same side and butted together. Option B is also incorrect because the joists are not usually lapped over the bearing wall in this way. Option D is incorrect because it describes a similar method as option A, but with lapping instead of butting.
