Abstract

Given the recent focus on recovery-based design, this study examines the effect of increased design strength and stiffness requirements on the functional recovery performance for a set of eight reinforced concrete moment frame archetypes. Each archetype is designed according to ASCE/SEI 7-16 and assessed using a recently developed performance-based framework for quantifying functional recovery. Results show that increasing the design base shear and limiting story drifts has a significant impact on structural performance and reduces the likelihood of severe structural damage leading to long recovery times. However, the structural improvements do not significantly reduce damage to critical nonstructural systems and are unable to reduce expected functional recovery times below 14 weeks for the design earthquake.
