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
DESCRIPTION Purpose: Provide measurement traceability for the Knoop, Rockwell, and Vickers hardness scales and for coating thickness measurements that are based on magnetic methods. Goals: Harmonization of hardness and coating thickness testing protocols, in pursuit of reduction of measurement
Objective: The project includes two critical tasks identified in Performance Based Seismic Engineering (PBSE): (1) use of simplified reinforced concrete wall models in high-fidelity nonlinear dynamic analysis that have no robust experimental data validation - to be solved by thorough experimental
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
