Diaphragm chord
WebJan 10, 2024 · Providing a chord (like (2) 2x6 top chords) isn't going to change the strains in other elements of the diaphragm or dormers anyway. The total deformation of a diaphragm isn't affected by the chords all that much as a larger proportion of your diaphragm deformation is shear-based. The chord does nothing to reduce that. WebDiaphragm Strength CLT shear values are based on ANSI/APA PRG-320, Standard for Performance-Rated Cross-Laminated Timber. V (in-plane shear strength) = t (thickness …

The truss supplier is modeling them as pinned roller, I will be making a positive attachment at each support.. • I have T&G deck topped with plywood to create a diaphragm. The trusses are exposed from below, so there is no ceiling diaphragm. WebA chord is a structural member along the boundary of a diaphragm that resists tension and compression forces. A collector is a struc- tural member that transmits diaphragm forces into shear walls or frames. Figure 2 depicts the overall function of chords and collectors.
