Guidelines for Post-Earthquake Repair and Retrofit of Buildings Based on Assessment of Performance-Critical Damage (P-2335)
Date Published: April 29, 2025
The resource provides guidance on the visual damage states for various structural components after an earthquake, focusing on reinforcement damage due to cyclic loading. It explains Damage States (DS) corresponding to different levels of structural integrity and provides tables and guidelines for the residual fatigue life of reinforcement in earthquake-damaged structures. The appendix also details the simplified method for assessing fatigue damage in reinforced concrete elements, including calculation of strain amplitudes, damage per displacement increment, and fatigue damage sum. Additionally, it outlines recommendations for more detailed fatigue life assessments using nonlinear response history analysis.
