What is the minimum bearing for a joist resting on steel?

The minimum bearing requirement for a joist resting on steel is 1 inch. This standard ensures that the joist has adequate support to safely carry the loads it will encounter. A 1-inch bearing provides sufficient surface area for the joist to distribute its weight onto the steel beam effectively.

This requirement is crucial for maintaining structural integrity and safety. Insufficient bearing can lead to issues such as bending or failure of the joist, which could compromise the entire structure. A bearing of 1 inch meets the necessary guidelines set by building codes and industry standards, providing a balance between safety and material use without being excessive.

Options that suggest less than 1 inch would not meet the necessary structural requirements, while those that propose more than 1 inch, although they may provide additional support, are not the minimum needed, thus making 1 inch the correct answer.
