Full-Scale House Fire Experiment for InterFIRE VR, May 6, 1998. Report of Test.

April 10, 2000
Author(s)
Anthony D. Putorti Jr., Jay A. McElroy
A public/private partnership involving multiple federal agencies and private industry was assembled to develop a comprehensive fire investigation training tool. The partnership consisted of the following federal agencies: the Bureau of Alcohol, Tobacco and

Compositional Analysis of NIST Reference Material Clinker 8486

April 1, 2000
Author(s)
Paul E. Stutzman, Germain Lespinasse, Stefan D. Leigh
Certification of the phase compositions of the NIST Reference Clinkers often is based upon more than one independent method. The current certificate values were established using an optical microscope examination, and additional microscope data taken from

Retrofit of Pre-Northridge Moment-Resisting Connections

April 1, 2000
Author(s)
S A. Civjan, M D. Engelhardt, John L. Gross
An experimental program was undertaken to evaluate methods to retrofit existing steel moment connections for improved seismic performance. Six full-scale subassemblages were tested under cyclic loading. Typical pre-Northridge connections were retrofit by

Simulation of Fluid Flow and Permeability in Cohesionless Soils

April 1, 2000
Author(s)
E Masad, B Muhunthan, Nicos Martys
This paper reports on a new laboratory methodology for the determination of the structure of pores, a method for the analysis of the data to obtain the statistics of the pore structure distribution, simulation of porous media with statistics consistent

The Past, Present, and Future of the Computational Materials Science of Concrete

April 1, 2000
Author(s)
Edward J. Garboczi, Dale P. Bentz, G J. Frohnsdorff
The computational materials science of concrete has developed rapidly in the last 15 years. This development has been strongly tied to the even more rapid advances in computer processor speed and memory during this same time, without which progress in the

Influence of Polymer Melt Behavior on Flammability (NISTIR 6588)

March 1, 2000
Author(s)
Thomas J. Ohlemiller, Kathryn M. Butler
As the initial step in a study of the role of polymer melt viscosity in polymer burning behavior, a simpler, non-burning configuration has been examined. Vertical slabs of two types of polypropylene have been subjected to uniform radiative heating on one

Automated Earthmoving Status Determination

February 28, 2000
Author(s)
William C. Stone, Geraldine S. Cheok, Robert R. Lipman
Efforts are underway at the National Institute of Standards and Technology (NIST) to develop automated non-intrusive production measurement systems and procedures for monitoring the status of general earthmoving operations at typical construction sites
