Data for Nonstructural Design Requirements for Functional Recovery Performance, in Development of Recovery-Based Seismic Design Requirements for the 2026 NEHRP Provisions

In the move toward design practices that facilitate recovery, there are ongoing efforts to reevaluate structural seismic design parameters such as design drift limits and response modification coefficients. These datasets are the product of work to support the development of the 2026 National Earthquake Hazards Reduction Program (NEHRP ) functional recovery design provisions. We proposed structural design requirements that limit the occurrence of safety-critical structural damage, i.e., damage that must be repaired for occupants to return to a building safely (Blowes et al., 2025a). We also proposed nonstructural design requirements for functional recovery (Blowes et al., 2025b) by evaluating the probability of meeting recovery time targets set by the Building Seismic Safety Council. The design checks are performed at a new risk-targeted Functional Recovery Earthquake (FRER) that follows a similar structure to current ASCE 7 Chapter 12 life-safety requirements. These datasets provide key inputs and outputs (e.g., engineering demand parameters, component fragilities, safety-critical structural damage data, recovery time data) from the calculations underpinning the 2026 NEHRP functional recovery provisions.
