Racking Performance of Light-Frame Walls Sheathed on Two Sides.
Abstract
Walls in light-frame construction resist in-plane shear forces, known as racking forces, by the interaction of the sheathing diaphragm and wood frame through the fasteners. Wall performance tests provide racking strength for a particular sheathing, fastener and wood frame configuration. Small-scale shear wall length (aspect ratio) on racking resistance, (2) additive nature of single-sided walls to determine racking resistance of double-sided walls, and (3) relative racking resistance of interior- and exterior-type wall construction. Results to an aspect ratio of 3 indicate strength and stiffness values relate linearly to wall length. Double-sided wall behavior can be predicted by summing single-sided wall values. On the basis of small-scale static tests, interior wall construction (gypsum sheathing) does provide significant racking resistance relative to racking resistance of exterior wall construction (plywood sheathing). This information will be helpful to building designers and code officials to determine racking resistance of shear walls.
