Once Again, Driven Piles are First

From this article about the discovery of settlements 3,000 years old around Lake Lucerne in Switzerland: Experts used radiocarbon analysis to date the artifacts to about 1000 B.C., when the lake level was more than 16 feet lower than it is today, writes Garry Shaw for the Art Newspaper. According to the statement, these conditions … Continue reading Once Again, Driven Piles are First

Yes, Civil Engineers, Things Move

A salutary reminder from Y. Ryabov's An Elementary Survey of Celestial Mechanics: There is of course no sense in asking why the planets rotate or why they have motion in general. Everything in the universe, from the smallest dust particle to colossal cosmic bodies, is in constant motion. There is no such thing as matter … Continue reading Yes, Civil Engineers, Things Move

Concrete Pile Head Response to Impact

Our newest research item is this one, which is an expansion of the work with steel piles earlier this year. Abstract is as follows: The application of semi-infinite pile theory to the behaviour of driven piles has been studied since Parola (1970). Most of the effort, however, has been concentrated on piles which do not … Continue reading Concrete Pile Head Response to Impact

OTC 5395 Revisited: Analysis of Cushioned Pile Hammers

This is a new paper to update and expand on part of the first technical paper presented by a Vulcan employee: the paper "A Proposal for a Simplified Model for the Determination of Dynamic Loads and Stresses During Pile Driving," originally presented at the 1987 Offshore Technology Conference.  The abstract is here: Warrington (1987) was … Continue reading OTC 5395 Revisited: Analysis of Cushioned Pile Hammers

The Limitations of Dynamic Formulae

In an earlier post Vulcan's advice on the limitations of dynamic formulae--specifically referencing the Engineering News Formula--was set forth.  That advice appeared in Vulcan's literature from 1906 to 1931.  Later in the 1930's Vulcan changed the way its literature was organised, and in the process Vulcan added new verbiage (a lot of it, really) to … Continue reading The Limitations of Dynamic Formulae

Is the Best Place to Run Old Windows Software…on Linux or a Mac?

A few years ago I put out an article entitled Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox, where I describe the use of DOSBox in running engineering software (and also Windows 3.1.)  A great deal of engineering software developed in the DOS era can still be used for engineering design … Continue reading Is the Best Place to Run Old Windows Software…on Linux or a Mac?
