Introduction to Dimensional Joists and Basic Function

What happens here

Begin by understanding the fundamental role of dimensional joists in a flooring system. Joists are structural members designed to span between two bearing points, such as a mud sill on a foundation or an I-beam/bearing beam. The required depth of a joist is determined by its span (the distance between bearing points) and the total load it is designed to carry. It's common to modify joists for plumbing and electrical installations, but these modifications must adhere to strict rules to maintain structural integrity.

Goal: Understand the purpose and fundamental principles of dimensional joists in construction.
