WebA diaphragm connection to transfer loads to the vertical shear wall system. Shear Walls Shear walls support the diaphragm and transfer lateral forces into the foundation. For small buildings, the exterior walls are often designed as shear walls to transfer all of the lateral forces to the foundation. WebFor most shear walls and diaphragms, fastener capacity will govern over sheathing capacity. A discussion of the mechanics-based approach and some experimentally derived adjustment factors can be found in Appendix B of APA’s Research Report 154: Structural Panel Shear Walls (Q260). These can be used to derive a system capacity. WebDiaphragm chord members are used to resist the tension and compression forces at the boundaries. This is also consistent AWC SPDWS Section 4.1.4 for Boundary Elements: Shear wall and diaphragm boundary elements shall be provided to transfer the design tension and compression forces. dauphin county population pa

CLT Diaphragm Design for Wind and Seismic Resistance

WebMar 24, 2009 · APA does not recommend screws for diaphragms (or shear walls) in high-seismic areas. Cyclic testing has shown that nails tend to bend and withdraw slightly rather than breaking and withdrawing completely. Even when partially withdrawn, nails retain some reserve withdrawal resistance. WebWood structural panel sheathed shear walls and diaphragms are the primary lateral-load-resisting elements in wood-frame construction. As wood-frame construction is continuously evolving, designers in many …
