The National Construction Safety Team has reached an important milestone in its investigation into the 2021 partial collapse of Champlain Towers South.
Objective The Functional Recovery project is designed to improve the time for recovery of key social functions by strengthening the built environment to withstand earthquake impacts. Our efforts will advance measurement science for the assessment and design of buildings and lifelines, contribute in
Objective This project aims to improve techniques currently used for risk evaluation (including uncertainty quantification) and mitigation (including FRP retrofit) of structural systems and integrate them within the PBEE framework. The first phase of the project is focused on the development and
Objective Develop acceptance criteria and modeling parameters of structural components for incorporation in performance-based methodologies and standards/codes for design of structures under multiple hazards. Technical Idea In performance-based engineering and design approaches, acceptance criteria
Classically, measurement of the mechanical properties and reliability of bulk-scale materials is performed with macroscopic specimens and methods. Specimen preparation limitations, miniaturized load-frame tooling problems, and inadequate understanding of the roles of specimen size and constraint on
