Abstract

Mid-rise wood-framed multi-unit residential buildings are becoming a common building form. Demising walls between adjacent dwellings are typically constructed of double-stud wall assemblies. Structural (shear) requirements often require the addition of structural sheathing on the inner face of the studs. There is limited laboratory test data to establish STC ratings for these walls; however, it is well understood that the sheathing layers can dramatically reduce the STC ratings of the walls.

This paper presents the results of numerous field (ASTC) tests done on double stud wall assemblies. The test results provide an indication of the degree to which interior structural sheathing lowers the ASTC ratings of these walls as well as the influence of the number of gypsum board layers on the ASTC ratings. These findings point to the need for a program of laboratory STC tests to establish STC ratings for these wall types.
