Improving Performance of Buildings in Very High-Seismic Regions Volume 1 – Methods, Findings, and Recommendations (FEMA P-2343)

This resource details the development of Equivalent Single-Degree-of-Freedom (eSDOF) models from more complex Multiple-Degree-of-Freedom (MDOF) models, focusing on wood light-frame and non-wood structural systems. It explains the use of the Equivalent Lateral Force (ELF) procedure and amplitude-dependent response properties for seismic analysis. Appendices provide step-by-step methods and considerations for deriving eSDOF models, emphasizing effective seismic weight and spectral response. The document is intended for professionals involved in seismic performance assessment and modeling of building structures.
