Abstract
The principal objective of the report is to summarize a research investigation into the in-plane shear response of plywood timber floor diaphragms. The in-plane shear force-deformation behavior of several full-scale 16 by 24 and 16 by 16-ft plywood-sheathed timber diaphragms in response to dynamic, and monotonic and cyclic static loading was evaluated. A mathematical model was developed to describe plywood-to-joist interaction. The principal objective of the experimental phase of the second stage of the investigation was to determine how timber diaphragm details influence behavior in response to large, in-plane shear deformations.
