Assessing Seismic Performance of Buildings with Configuration Irregularities (FEMA P-2012)

This resource analyzes the seismic performance of buildings with configuration irregularities, focusing on collapse risk assessment using OpenSees and ATENA models. It evaluates how architectural configurations and structural features, such as story stiffness reductions, openings, and vertical irregularities, affect collapse probabilities, margin ratios, and deformation capacities in reinforced concrete wall buildings. The study applies Design Spectra and Maximum Considered Earthquake Response Spectra procedures to assess collapse risk. It is intended for professionals involved in seismic assessment and design of buildings.
