000011649 520__ $$2eng$$aActivities over the last few years within the NEESWood project have focused on the development of a performance-based seismic design philosophy for woodframed structures. One approach to improving the performance of such structures is to utilize an advanced seismic protection system (e.g., a seismic isolation or damping system). Full-scale testing of an energy dissipation system within a woodframed building has been conducted by the authors as part of the NEESWood project. The testing involved the application of prefabricated modular damper walls to a two-story, 1,800 sq ft woodframed townhouse structure that was tested on the seismic shaking tables at the University at Buffalo NEES site. Based on what was learned from this testing, a new toggle-braced design for the modular damper walls was developed and is currently undergoing testing This paper presents a displacement-based design procedure for application of toggle-braced linear viscous dampers to multistory woodframed structures. The procedure was originally developed within the NEESWood project and in this study is further extended to include the application of a damping system. The procedure requires simple modal analysis and determination of equivalent stiffness based on the backbone response of the shearwalls. As an illustrative example, the design of the benchmark test structure retrofitted with a toggle-braced damping system is presented. The validity of the proposed displacement-based procedure is confirmed using results from nonlinear dynamic response-history analyses.
