31. Fire Performance of High Strength Concrete: Research Needs
Published: 5/1/2000
Authors: Long Thanh Phan, Nicholas J. Carino
Abstract: A compilation of fire test data which shows distinct behaviroal differences between HSC and NSC at elevated temperature is presented. The differences are most pronounced in the temperature range of 20 {degrees}C to 400 {degrees}C. What is more import ...

32. Heating, Spalling Characteristics and Residual Properties of High Performance Concrete
Published: 3/1/2000
Authors: Long Thanh Phan, James R. Lawson, Frank L. Davis
Abstract: Results of part of an ongoing research program, being conducted at the National Institute of Standards and Technology (NIST) to study effects of elevated temperature exposure on performance of high performance concrete (HPC), are presented. One of t ...

33. Experimental Plan for Testing the Mechanical Properties of High-Strength Concrete at Elevated Temperatures (NISTIR 6210)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6210
Published: 5/1/1999
Authors: Long Thanh Phan, Richard D Peacock
Abstract: This report outlines an experimental plan designed to quantify the effect of elevated temperature on the mechanical properties of high-strength concrete. The experimental program will examine the influences of the following factors: (1) different st ...

34. The Fujita Tornado Intensity Scale: A Reassessment From Structural Engineering Perspective
Published: 5/1/1999
Authors: Long Thanh Phan, Emil Simiu
Abstract: This paper is a condensed version of two previous publications: NIST Technical Note 1426, by Long T. Phan and Emil Simiu; and ASCE Civil Engineering magazine article Tornado Aftermath: Questioning the Tools, by Long T. Phan and Emil Simiu.

35. Fujita Tornado Intensity Scale: A Critique Based on Observations of the Jarrell Tornado of May 27, 1997 (NIST TN 1426)
Series: Technical Note (NIST TN)
Report Number: 1426
Published: 7/1/1998
Authors: Long Thanh Phan, Emil Simiu
Abstract: On May 27, 1997, several tornadoes hit the Central Texas area in the counties of McLennan, Bell, Williamson, and Travis. The most destructive of these tornadoes swept through a housing area on the outskirts of Jarrell, Texas. Jarrell is a Central Tex ...

36. Post-Installed Anchors. A Literature Review
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6096
Published: 1/1/1998
Authors: Geraldine S Cheok, Long Thanh Phan
Abstract: A literature review of studies on the behavior of post-installed concrete anchors is presented. The survey covers several types of anchors that are subjected to tension loads, shear loads, and to combined shear and tension loads. Brief summaries of ...

37. Review of Mechanical Properties of HSC at Elevated Temperature
Published: 1/1/1998
Authors: Long Thanh Phan, Nicholas J. Carino
Abstract: A compilation of experimental results on the mechanical properties of concrete when exposed to rapid heating as in a fire are presented. Emphasis is placed on concretes with high original compressive strengths. That is, high-strength concretes (HSC ...

Series: Special Publication (NIST SP)
Report Number: 919
Published: 9/1/1997
Author: Long Thanh Phan
Abstract: This report documents the presentations and discussions that were made at the NIST workshop on fire performance of high-strength concrete. The workshop was held at NIST in Gaithersburg, MD on Feb 13-14, 1997 in collaboration with the Portland Cement ...

39. Analytical Modeling for Soil-Structure Interaction of a 6-Story Commercial Office Building.
Published: 7/10/1994
Authors: Long Thanh Phan, E M Hendrickson, R D Marshall, M Celebi
Abstract: Strong-motion and ambient vibration data obtained from a 6-story commercial office building in San Bruno, California, were analyzed. Comparison of dynamic characteristics revealed that the first-mode response frequency deduced from the Loma Prieta ea ...
