Building-Level Seismic Performance Assessment

Ongoing
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

Robust Structural Systems for Multi-Hazard Mitigation

Ongoing
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

NIST Proficiency Testing

Ongoing
A typical lot of NIST SRMs has 300 units, with 5 specimens in each unit. These SRMs are tested by customers and the customer verification data is returned to NIST for evaluation according to the requirements of ASTM E23. Once a minimum of 50 verification results are returned to NIST for a particular
Running crack in a buried pipeline.

Pipeline Safety

Ongoing
The U.S. operates more than 2.5M miles of natural gas, petroleum and hazardous liquid pipelines, crossing all 50 states and operated by more than 3,000 companies. Fluid hydrocarbon fossil fuels remain the world leading source of energy. The safest and most reliable means of transporting these fuels
