Are joists designed to take vertical loads?

1. True

2. False

3. Sometimes

4. Depends on the material

The correct answer is: False

Joists are actually designed to support vertical loads, which include the weight of the structure, furniture, occupants, and any other loads that will be placed on them. Joists are horizontal structural members that help to distribute these loads to other structural elements, such as beams or walls. When properly installed and spaced according to engineering standards, joists effectively handle the vertical forces they encounter. In this context, saying that joists do not take vertical loads would be inaccurate. They play a crucial role in load-bearing within various types of construction, particularly in floors and ceilings. The materials used for joists—such as wood, steel, or engineered lumber—contribute to their strength and ability to support these loads. However, the essential function of a joist itself remains consistent across materials; they are fundamentally designed to carry vertical loads safely and effectively.
