Final answer:
Floor joists should only be spliced over bearing points as this provides the best stability and weight distribution. Splicing at any location or at random intervals can compromise the joist’s structural integrity unless properly supported.
Step-by-step explanation:
In the context of construction and engineering, splicing floor joists, which means joining two pieces of floor joists together, is considered a critical procedure and must be done correctly to ensure structural integrity. Typically, floor joists should only be spliced over bearing points. This is because a bearing point can adequately support the load being placed on the joist. Splicing over bearing points provides for the best stability and weight distribution.
You do not generally splice floor joists anywhere or at random intervals such as every 8 or 4 feet because it can compromise the strength and stability of the joist unless a specific design requires it and it is properly supported.
Therefore, the correct answer to your question is d. only overbearing points.
