Cumulative Seismic Damage of Circular Bridge Columns: Variable Amplitude Tests

September 1, 1999
Author(s)
A El-Bahy, S K. Kunnath, William C. Stone, A W. Taylor
The findings from an experimental study to investigate cumulative seismic damage in reinforced concrete circular bridge piers is presented. Twelve identical quarter-scale bridge columns, designed in accordance with current AASHTO specifications, were

Digital Library Support for Engineering Design and Manufacturing

September 1, 1999
Author(s)
William Regli
This paper describes our initial efforts to deploy a digital library to support engineering design and manufacturing. This experimental testbed, The Engineeting Design Repository, is an effort to collect and archive public domain engineering data for use

Elemental Data Index

September 1, 1999
Author(s)
M A. Zucker, Robert A. Dragoset, A R. Kishore
The Elemental Data Index provides access to the holdings of NIST Physics Laboratory online data organized by element. It is intended to simplify the process of retrieving online scientific data for a specific element. Data accessible through this index

Enhancing Collaboration using an Internet Integrated Workbench

September 1, 1999
Author(s)
Robert Allen, Srinivas Nidamarthi, S P. Regalla, Ram D. Sriram
We report on our experience using an Internet-based collaborative environment to enhance the design and manufacturing process of a custom-designed artifact transport system (ATS). Specifically, we focus on overcoming the hurdles associated with exchanging

Fundamental Constants, QED, and the Proton Form Factor

September 1, 1999
Author(s)
Peter J. Mohr, Barry N. Taylor
Most of the fundamental constants are obtained by the comparison of the results of critical experiments and theoretical expressions for these results. Many of the theoretical expressions are based on quantum electrodynamics (QED), so the consistency of the

Global Model for Predicting the Burning Rates of Liquid Pool Fires (NISTIR 6381)

September 1, 1999
Author(s)
Anthony P. Hamins, Jiann C. Yang, Takashi Kashiwagi
A global model is presented which predicts the mass burning flux for pool fires consuming liquid fuels in a quiescent environment. the model assumes constant bulk properties such as flame temperature, soot volume fraction, and species concentration. The

Incoporating Process Planning into Conceptual Design

September 1, 1999
Author(s)
Shaw C. Feng, Gordon A. Shaw, Walter W. Nederbragt, Serge Kaing, Ram D. Sriram
This paper describes recent developments in the Design and Process Planning Integration (DPPI) project at the National Institute of Standards and Technology (NIST). The project addresses the need for improved communication between design and process

Information Modeling: From Design to Implementation

September 1, 1999
Author(s)
Yung-Tsun T. Lee
Today's manufacturing industry greatly relies on computer technology to support activities throughout a product's life cycle. Effective and efficient information sharing and exchange among computer systems have been critical issues. Formal information
