After using joist spacing to calculate the number of ceiling joists needed when the joists will be spliced above a loadbearing partition, how many additional joists should be added? 1 2 3 4

When calculating the number of ceiling joists needed when the joists will be spliced above a loadbearing partition, it is generally recommended to add one additional joist for every four joists that will be spliced. This is because splicing joists can create a weak point in the structure, and adding an extra joist can help to distribute the load more evenly and provide additional support.<br /><br />Therefore, the correct answer is 2.
