MetadataShow full item record
The NSF sponsored CFS-NEES1 project R-CR: Enabling Performance-Based Seismic Design of Multi-Story Cold-Formed Steel Structures project was undertaken to study the behavior, particularly seismic behavior, of light-framed structures using cold-formed steel cee-sections as the primary gravity load carrying elements with wood structural panel diaphragms and shearwalls as the primary lateral load resisting system. Devco Engineering, Inc. was selected to develop design calculations and drawings for the structure based on criteria determined by the research team. Input on the details of design was also sought from industry professionals through the Industry Advisory Board (IAB)2. The details developed in the design phase will be studied via component and full-scale shake table testing of the structure. This report discusses the design of the gravity and lateral systems for the CFS-NEES building. Specific calculations and drawings are attached herewith as appendices for reference.
