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

This document presents a methodology for evaluating the collapse potential of older concrete buildings during earthquakes. It details procedures for estimating base shear strength and assessing the risk of global loss of vertical load-carrying capacity in building stories. The methodology uses probabilistic approaches to characterize seismic demand and capacity limits, enabling efficient screening of building inventories for collapse risk. It is intended for professionals involved in seismic risk assessment and mitigation of existing concrete structures.
