This report, Seismic Evaluation of Older Concrete Buildings for Collapse Potential (FEMA P-2018), provides a simplified methodology for evaluating collapse resistance using simplified estimates of drift demand. The calculations have been intentionally simplified; however, the underlying criteria are based on probabilistic concepts and structural reliability theory. Development of the procedures included testing of the methodology by practicing engineers in several rounds of trial evaluations, and vetting of the methodology in a series of annual workshops. All of this was used to adjust and improve the methodology throughout the development process.
