Staggering of joists at quarter points [see Sentence 9.23.8.3.(3)] and effective width of built-up lumber beams, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

Intent
Intent 1: 
To limit the probability of coinciding joints, which could lead to inadequate bending strength at butt joints between pieces of lumber, which could lead to an inability to resist expected gravity loads, which could lead to failure of the beam, which could lead to structural collapse, which could lead to harm to persons.
