Improvement of Nonlinear Static Seismic Analysis Procedures (FEMA 440)

FEMA This state-of-the-art resource captures the latest advances in nonlinear static analysis. It evaluates FEMA and Applied Technology Council (ATC) procedures for estimating the response of structures to ground shaking and attempts to address the significantly different results in estimates of maximum displacement that these procedures generate. This report sets the stage for future improvements to FEMA 356 or the ATC report, Seismic Evaluation and Retrofit of Concrete Buildings (ATC-40). The CD-ROM, FEMA 440CD, June 2005, contains the document (FEMA 440) and supplementary summaries in PDF files.
