What is the minimum bearing required for the ends of a ceiling joist on wood?

The minimum bearing required for the ends of a ceiling joist on wood is 1 1/2 inches. This requirement is established in building codes to ensure that the joist has sufficient support to transfer loads safely and effectively to the supporting structure. A bearing of 1 1/2 inches allows for adequate contact area between the joist and the support, which helps prevent potential issues such as bowing or failure under load. Additionally, this dimension has become a standard practice in construction, making it an important aspect of ensuring structural integrity and longevity in roofing and ceiling systems.
