System Performance of Wood Header Assemblies

This study investigates the bending load performance of single wood members, double wood members (i.e., headers), and multiple wood members including floor framing. Findings detailed in this report include that significant system effects are present in typical wood frame header assemblies, and that a repetitive member bending stress increase factor is applicable to double member systems. These findings are intended to improve the efficient design of wood headers in typical light frame wall systems. Prepared for the U.S. Department of Housing and Urban Development and the National Association of Home Builders by the NAHB Research Center.
