Ralph B. Peck 1912 – 2008


Ralph B. Peck, Professor Emeritus of Foundation Engineering at the University of Illinois at Urbana-Champaign died of congestive heart failure on February 18, 2008, at his home in Albuquerque, New Mexico. He was born in Winnipeg, Canada, to his American parents, Orwin K and Ethel Huyck Peck on June 23, 1912.

Ralph Peck earned a Civil Engineering Degree in 1934 and Doctor of Civil Engineering Degree in 1937, both from Rensselaer Polytechnic Institute in Troy, New York. In 1938-39 he attended the Soil Mechanics course at Harvard University and was a laboratory assistant to Arthur Casagrande. From 1939 to 1942 Peck was an assistant subway engineer for the City of Chicago, representing Karl Terzaghi who was a consultant on the Chicago Subway Project. He joined the University of Illinois in 1942, and was a Professor of Foundation Engineering from 1948 to 1974. Since 1974, Professor Peck was a Professor Emeritus at the University of Illinois, and a consultant in geotechnical engineering.

In 1948, together with Karl Terzaghi, Ralph Peck co-authored the most influential text book in geotechnical engineering, Soil Mechanics in Engineering Practice. In 1953 with Walt Hanson and Tom Thornburn, Ralph Peck co-authored the widely used text book Foundation Engineering.

In 1942, Dr. Peck joined the Civil Engineering Department of the University of Illinois, where he remained as a teacher and mentor until his retirement as Professor Emeritus in 1974. After moving to Albuquerque, Dr. Peck continued his active consulting practice which included jobs in forty-four states in the USA and twenty-eight countries on five continents. His more than one thousand consulting projects include: the rapid transit systems in Chicago, San Francisco, and Washington; the Alaskan Pipeline System; the James Bay Project in Quebec; and the Dead Sea dikes. He authored over 250 technical publications, and served as the President of the International Society of Soil Mechanics and Foundation Engineering from 1969 to 1973. In 1974, he was awarded the National Medal of Science by President Ford. A few of his many honors include the Norman Medal, The Wellington Prize, and the Outstanding Lifetime Achievement Award in Education from the American Society of Engineers. His last project was the Rion-Antirion Bridge in Greece. It received the ASCE’s OPAL Outstanding Civil Engineering Award for 2005, and is the only project outside the United States to be so honored.

Ralph Peck married Marjorie E. Truby on June 14, 1937. He is survived by his daughter and son-in-law, Nancy Peck (Allen) Young, and son and daughter-in-law, James (Laurie) Peck, and grandchildren, Michael Young and Maia Peck.

Rebar Corrosion Blamed For Most Construction Failures


Two Greek Scientists have published a paper in Construction and Building Materials citing the corrosion of steel rebar in concrete as the number one cause of construction deterioration. They say that current models for corrosion may over predict the service life of structures especially in corrosive environments. They found good agreement of salt spray accelerated corrosion tests on bare steel bars with results from concrete embedded steel bars

Autodesk Reports Record Revenues of $538 Million


I don't know how much of an economic indicator Autodesk, Inc. (NASDAQ: ADSK) is but I figure it might be some kind of leader. Companies probably don't buy design software when there are no buyers for the end product. Anyway, the title says, Autodesk broke their record for Q3 revenues. Model-based 3D products, Inventor, Revit, Civil 3D and newly acquired NavisWorks software increased 32 percent over the third quarter of fiscal 2007 to $130 million and comprised 24 percent of total revenues. Happy Birthday!

UPDATE: Australian Landslide


The landslide occurred yesterday along near a coal mine that supplies the Yallourn
powerplant
, one of the largest in the state of Victoria. Heavy rainfall this month has increased pressure on the mines wall. Engineers assessed the mine walls last week for seepage but reported no indications of eminent failure.

The adjacent Latrobe River has been entering the mine since the slide. Remediation will probably include rerouting the river to supply downstream dams and lakes which are now only receiving minimal flows from urban runoff.

The powerplant which usually supplies 22% of Victoria's electricity has been running at a reduced capacity of 30% since the failure. The mine produces around 18 million tonnes of high moisture brown coal to the powerplant annually using gps guided CAT D11s like this:

Holland Tunnel Turns 80


This week marked the 80th anniversary of the opening of the Holland Tunnel from Jersey City to Manhattan. The tunnel's two 20 foot diameter tubes are 8,558 ft and 8,371 ft long. Named after it's design engineer, Clifford Holland, it is situated in bedrock 93 feet below the mean water level of the Hudson River. The tunnel was the first twin tube, underwater vehicle tunnel in the U.S. and the world's first mechanically ventilated vehicular tunnel. The Holland Tunnel was declared a National Civil Engineering Landmark in 1984 by the ASCE.
