Performance of Wood Structural Panel Shear Walls Under Cyclic (Reversed) Loading
Research Report 158. Testing sponsored by APA and conducted at University of California – Irvine, using modified TCCMAR procedure. (Form W260 - 40 pages)

Narrow Walls That Work
Provides recommended construction details for a moment-resisting narrow wall section. The APA Narrow Wall Bracing Method design provides the strength and stiffness of a bracing unit, and offers options for engineered designs. (Form D420 - 8 pages)

Technical Note: Narrow Wall Bracing Without Hold Downs for Use in a Fully Sheathed House
Construction details of APA's Narrow Wall Bracing Method for 6:1 aspect-ratio wall segments on raised wood floors. The tested design requires no hold downs to perform equivalent to current 4:1 aspect ration bracing requirements of the 2003 IRC. The detail has been proposed for incorporation in the 2004-05 code-change development cycle. (Form E425 - 4 pages)
