Boulanger, Kutter, Malvick and Kulasingam Awarded Norman Medal

Norman

Ramachandran Kulasingam, A.M.ASCE, Erik Malvick, Ph.D., A.M.ASCE, Ross W. Boulanger, P.E., M.ASCE, and Bruce Kutter, Ph.D., M.ASCE, have been named the recipients of the of the *Norman Medal* for their paper “Strength Loss and Localization at Silt Interlayers in Slopes of Liquefied Sand,” which appeared in the November 2004 issue of ASCE’s Journal of Geotechnical and Geoenvironmental Engineering.

The Norman Medal is bestowed upon the author or authors of a paper that is judged worthy of special commendation for its merit as a contribution to engineering science. ASCE has thirty journals and the Norman Medal is for the best paper from all of them that year.

The paper signalized with this year’s medal investigates the role of void redistribution in the liquefaction behavior of saturated sand slopes with and without silt interlayers. The authors report experimental and analytical results demonstrating that the apparent residual shear strength is unlikely to correlate closely with preearthquake penetration resistance alone; rather, it is a function of these initial shear stresses and numerous factors affecting the process of void redistribution and localization.
