What type of loads do joists primarily transfer?

1. Static loads

2. Live loads

3. Contracted loads

4. Environmental loads

The correct answer is: Live loads

Joists are primarily designed to support and transfer live loads. Live loads refer to the variable forces that act on a structure during its use, such as people, furniture, and other movable items. These loads can change in magnitude and location over time, thus requiring a flexible and robust support system like joists to handle these variations without compromising the integrity of the structure. While static loads, which include the weight of the building materials and any permanent fixtures, are also considered in the overall design of a structure, joists specifically focus on carrying live loads to ensure safety and functionality. Contracted loads and environmental loads, such as wind or seismic effects, play a role in the overall structural design but are not the primary function of joists. The emphasis on live loads highlights the importance of adaptability in construction, as these loads fluctuate more frequently than static conditions.
