John H. Schmertmann

from Wikipedia, the free encyclopedia

John Henry Schmertmann (born December 2, 1928 in New York City ) is an American civil engineer ( geotechnical engineering ).

Schmertmann studied civil engineering at the Massachusetts Institute of Technology ( Bachelor 1950) and at Northwestern University , where he received a master’s degree in 1952 and his doctorate in 1962. 1951 to 1954 he worked as a geotechnical engineer with Moran, Proctor, Mueser and Rutledge in New York and then until 1956 with the US Army Corps of Engineers. From 1956 he was first assistant professor and later professor of civil engineering and coastal engineering at the University of Florida . He is now Professor Emeritus there. 1962/63 he was a Fellow of the National Science Foundation at the Geotechnical Institute in Oslo and 1971/72 visiting scientist at the National Research Council of Canada. From 1978 he also worked in his own engineering office Schmertmann & Crapps Consulting Geotechnical Engineers.

In 1970 Schmertmann proposed a new method using pressure probing (CPT) to estimate the stiffness modulus of the soil and, from this, the settlement of shallow foundations in sandy soils (from the values ​​of the peak pressure during pressure probing). He also further developed the CPT methods, as in the early 1970s, through simultaneous pore water pressure measurements in addition to peak pressure and skin friction.

In 1989 he gave the Terzaghi Lecture . In 1956 he received the Collingwood Prize from the American Society of Civil Engineers (ASCE), the State of the Arts Award from the ASCE (1977), the Middlebrooks Prize, the Lifetime Achievement Award from the ASCE and in 1971 the Norman Medal from the ASCE. He is a member of the National Academy of Engineering (1984).

John Henry Schmertmann is married and has four children.
