Problems with Metrication in Transboundary Water Projects
This presentation discusses the lessons learned and difficulties encountered by the author in the conversion to SI (System International or modernized metric system) and provides a brief...
Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...

Blast Wall Bravura
Since the 1988 disaster on the Piper Alpha platform in the North Sea, which claimed 165 lives, legislation in the United Kingdom has required the operators of offshore installations to...
Starting a Project
Project start-up marks the end of the planning activities and the beginning of the project. The PM must take the steps necessary to set up job numbers, job data sheets, assemble data needed...
The Northridge Fractures: Are We Learning the Right Lessons?
After the Northridge earthquake in January 1994, engineers found problems with special moment-resisting frames. There were multiple facture modes, and typical damage involved primary crack...
A Safer Earthquake Design Code After NorthRidge
Three recent killer California earthquakes have demonstrated serious deficiencies in our current building codes. As they do after all such events, officials in California and other states...
Gaining Project Acceptance
Involvng every constituency early in the development of public works projects can build acceptance even when parties don't get exactly what they want. Two Illinois transportation...
Lessons from Nonfailures
Two case histories are described in which building owners were told during rehabilitation projects that their structures were in serious trouble. In one case, the engineer told the owner...
The Winds of Change?
In 1992, Hurricanes Andrew and Iniki combined to generate an estimated $30 billion in damage. The storms also generated their share of reports and recommendations about how best to mitigate...
Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...
Remote Sensing of AstrofuelTM
A direct, high-resolution measurement from lunar orbit of the location of high concentrations of 3He in the lunar regolith is needed for the initiation...
Understanding ISO
Many U.S. consulting firms are being registered under the International Organization for Standardization (ISO) 9000 series, which set standards for business conduct to achieve quality....
Representation and Processing of Design Standards: a Bifurcation between Research and Practice
There have been attempts to develop representations of design standards and procedures for computing representations of the design standard on which computations are based. However, within...
Qualification System for Building Engineers in Japan
Recently, it has become common for structural engineers to provide consulting services beyond their countries. Thus it is important that they become fully acquainted with the working conditions...
Lateral Buckling: A Comparison of AISC-LRFD and Eurocode 3
The nominal moment capacity of laterally unsupported, doubly-symmetric, steel I-beams are computed and compared using the AISC-LRFD and EC 3 design recommendations. A review of the EC...
Proposed Hurricane Wind Speeds for ASCE 7-95
A 2-3 second peak gust wind map has been proposed for the wind load provisions of ASCE 7-95, now in draft form. On the hurricane coast, speeds from published Monte Carlo analyses were...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
Harmonization of Reliability-Based Timber Engineering Codes and Standards
An overview of activities related to harmonization of reliability-based timber design codes and standards is presented. The overview is based on information generated through a NATO Advanced...
