Evidence from recent disasters, including the earthquakes of Northridge (CA, 1994), Christchurch (NZ, 2011), Hurricane Maria (Puerto Rico, 2017), and other natural hazards, has illustrated how damage to buildings and infrastructure throughout a region can interrupt businesses, displace households, and significantly disrupt the function of the community for years to come (Mieler & Mitrani-Reiser, 2017). The downtimes and indirect losses induced by these events have motivated policymakers and the engineering community to target new design guidelines and retrofit policies that reduce the vulnerability of the built environment through improved building functional recovery performance objectives (e.g. EERI, 2019; NIST & FEMA, 2021). To improve building performance to meet these new standards, engineers have turned toward performance-based earthquake engineering and design standards to explicitly quantify building performance, probabilistically communicate uncertainty, and develop new design strategies to improve building performance. However, current methods often rely on a conservative worst-case architecture to aggregate that component-level performance into global building performance objectives, do not explicitly consider the quantification of building function, and have limited validation against empirical earthquake data, and are, therefore, not well calibrated for modern resilience objectives.The main objective of this dissertation is to identify the key differences between the scope of current performance-based assessment methods and the complexities in modeling modern recovery-based performance objectives and develop new performance-based methods to address these gaps. This dissertation benchmarks outcomes from ASCE/SEI 41 and FEMA P-58 against recorded earthquake data, proposes alternative means of assessing collapse prevention performance through ASCE/SEI 41, proposes updates to the repair costs and unsafe placard assessments in FEMA P-58, and proposes a new performance-based approach to systemize component-based damage and explicitly define global building functional recovery performance. With an expanded scope towards recovery-based performance objectives, the performance-based methods proposed in this study are used to quantify the expected functional recovery performance of modern code conforming buildings, identify any gaps between the expected performance of current design standards and desired outcomes, and recommend potential design strategies to improve building performance.
