Seismic Evaluation of Older Concrete Buildings for Collapse Potential (FEMA P-2018)

The document outlines the evaluation methodology for identifying and mitigating seismic hazards in older concrete buildings. The methodology focuses on determining the relative risk of collapse in these buildings during strong earthquake shaking. It incorporates mechanisms to estimate base shear strength and evaluates the global loss of vertical load-carrying ability in a story that can potentially lead to collapse. The methodology includes probabilistic characterization of demand and capacity limit, providing a measure of collapse for critical column and wall components in each story, and for the collapse of a story as a whole. The approach aims to efficiently screen an inventory of older concrete buildings for collapse potential.
