In which components would you find collar ties utilized?

Collar ties are primarily utilized in roof framing. Their main function is to help support the roof structure by connecting opposite rafters, typically at the upper third of the roof. This connection helps to prevent the rafters from spreading apart under the weight of the roof, especially in areas that experience high wind loads or heavy snow accumulation. By providing lateral support, collar ties contribute to the overall stability and strength of the roof system, ensuring that it maintains its shape and integrity over time.

In contrast, floor joists are designed to support floors, wall sheathing serves to provide structural support and insulation to walls, and load-bearing beams transfer loads from the roof and upper floors down to the foundation. While each of these components plays an essential role in a building's structural system, collar ties specifically pertain to the roofing framework.
