Science of Concrete--Fundamental Models that Enable New Technology for Expanded Use of Fly Ash and Performance-Based Seismic Design Methods and Tools for Reinforced Masonry Shear Wall Structures are among 27 projects to receive funding from NIST, which operates within the U.S. Department of Commerce.
NIST has awarded $1.5 million to the University of California, San Diego (UCSD) for Masonry Shear-Wall Structures. Centered at the school's La Jolla lab, the three-year project targets a) innovative methodologies and improved design requirements for seismic resistance of shear walls in reinforced masonry buildings; and, b) reliable analytical tools for assessing seismic performance and wall design methodsÌ cost-effectiveness. Current design methods and code requirements for shear walls in reinforced masonry buildings are occasionally impractical, especially for commonly encountered low-rise buildings that have walls with many openings, researchers contend. Moreover, some of the prescriptive requirements for masonry shear walls have not been fully substantiated with experimental research, they add, potentially resulting in misplaced provisions for ductility.
Announcing the $34 million in grants for the Fly Ash, Masonry Shear Wall and 25 other studiesÛattributable to the American Recovery and Reinvestment ActÛCommerce Secretary Gary Locke noted, These new projects will create high-tech jobs and spur economic growth while supporting U.S. world leadership in science.
"These projects will bolster U.S. scientific and technological infrastructure, increasing our nation's ability to innovate, compete, and solve scientific and technological problems," adds NIST Director Patrick Gallagher.
