The National Construction Safety Team has reached an important milestone in its investigation into the 2021 partial collapse of Champlain Towers South.
Objective: To better understand the seismic performance of buildings designed in areas of medium-to-high seismicity and to identify ways to create enhanced performance through low-damage approaches, improved code provisions, and improved analysis procedures. What is the Problem? Despite progress
Objective - To develop next-generation methods and tools to better characterize extreme wind hazards and associated loads, and response of structures to extreme winds, thus enabling performance-based standards for designing structures that resist extreme winds. What is the new technical idea? The
Objective - Develop performance-based design methods for structural systems to achieve robustness against multiple hazards, including extreme winds and disproportionate collapse.
What is the new technical idea? The new technical idea is to develop and demonstrate effective strategies for
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
