Summary
This project is aimed at meeting the needs of mass timber design industry by developing a numerical modeling guide for multi-story wood buildings with post-tensioned rocking wall lateral systems. Through close collaboration of researchers, practicing engineers, and software developers, three main deliverables will be generated from this project. The first one is a tall wood modeling guide which provide detailed suggestions on mass timber building modeling options and processes using commercial programs widely available in design offices. One or multiple of PERFORM-3D, ETABS and SAP2000 packages will be used in this study. The second deliverable will be a mass timber dynamic response validation data package based on full-scale dynamic testing results from two- and ten-story mass timber buildings. This package contains building design detail and dynamic test responses, which can be used by design engineers to validate their own numerical model for performance-based seismic design or approval for new mass timber projects. Finally, the third deliverable will be a show-case archetype building modeling example in which a 6-story office building will be designed and modeled for a high seismic region location. The example will demonstrate typical steps a design engineer can follow to design and model such a building for review and approval by building officials.
