A pilot study was conducted at Penn State University to determine whether the type ofdrywall joint compound would influence the shear strength of wood-frame studwalls sheathed with Gypsum Wall Board GWB or drywall. In this study, five2438 mm by 2438 mm specimens were tested under in-plane cyclic racking loadingfollowing the CUREE loading protocol for light-frame wall systems. Three specimens were finished using non-cementbased joint compound while the other two used cement based joint compound.Based on the experimental testing of the specimens, the results show that theuse of cement based joint compound on drywall joints produces higher shearcapacity for the wall system as compared to similar specimens finished withconventional non-cement based joint compound. The result of the study isparticularly important for high seismic regions where interior stud walls inresidential construction effectively take part in seismic resistance eventhough wood shear walls are normally used on exterior walls.
