1 inch
1 1/4 inches
1 1/2 inches
2 inches

The correct answer is: 1 1/4 inches

The standard width of the base of load-bearing steel joists is 1 1/4 inches. This dimension is important for ensuring proper load distribution and compatibility with standard structural connections and other components of a building's framework. The specific measurement of 1 1/4 inches allows for effective engagement with supports and helps in maintaining structural integrity, ensuring that the loads transferred to the supporting structures are managed correctly. The choice of 1 1/4 inches aligns with industry standards and practices, ensuring that these joists can efficiently support the design loads specified in engineering calculations and building codes. Understanding these dimensions is crucial for general contractors when selecting materials and planning for safe and compliant construction practices.
