Abstract: Cross laminated timber (CLT) based Seismic Force Resisting Systems (SFRS) are not yet recognized in the U.S. design codes and therefore seismic design can only be performed through alternative methods. The purpose of this Forest Products Laboratory funded research project currently underway at Colorado State University is to identify seismic performance factors for CLT as a SFRS. The study is based on the FEMA P-695 methodology that provides a systematic, logical, and relative approach consisting of nonlinear static and dynamic analyses. There are several phases to the project including the development of the archetypes, design methodology, testing, modeling, and the full P-695 analysis procedure itself. This presentation includes a brief description of the FEMA P-695 methodology along with the recent progress on the test program. CLT archetypes developed as part of this study and nonlinear models used to simulate CLT behavior at the connector, wall, and system levels are presented. Some examples of several performance groups within the methodology will be presented in their preliminary form, and the procedure to determine the collapse margin ratio will be explained. The timeline to completion has been updated and will be provided.
