OTC 5397 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 5397 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?

Picking Up Concrete Piles for Driving

One of the concepts students in geotechnical engineering courses seem to have the most trouble with is estimating stresses in concrete piles during pick-up and setting them in place to drive.  The basic problem is that it's sometimes hard to get our heads around the analytical simplification of the actual situation.  Let's start by looking … Continue reading Picking Up Concrete Piles for Driving

A Sea Fight in a Fog: Revisiting the ASCE Controversy about Dynamic Formulae

It's always good for geotechnical professors and practitioners alike to think about where our industry has been and where it’s headed.  A little while back three of our most eminent people (Garland Likins, Bengt Fellenius and Robert Holtz) came together and wrote an excellent piece for the 2Q 2012 issue of the Pile Driver (the … Continue reading A Sea Fight in a Fog: Revisiting the ASCE Controversy about Dynamic Formulae

Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox

It’s been a long time since many computers ran DOS or even Windows 3.1.  Given the changes in hardware, it would be difficult to get most any recent PC to run one or both.  Yet every time we have a major software upgrade, we lose some of the capabilities we had in the past.  It’s … Continue reading Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox
