The Effect of Environmental and Mechanical Mechanisms on the Performance of Soft Body Armor

July 27, 2009
Author(s)
Gale A. Holmes, Eun S. Park, Jae Hyun Kim, Walter G. McDonough, John R. Sieber, Haruki Kobayashi, Michael A. Riley, Kirk D. Rice
The use of high performance fibers (such as, poly[(benzo-[1,2-d;5,4-d ]-benzoxazole-2,6-diyl)-1,4-phenylene]1 (PBO), ultra-high molecular weight polyethylene2 (UHMWPE), and poly(p-phenylene terephthalamide)3 (PPTA)) in soft body armor (SBA) is well

Ballistic Resistance of Body Armor.

July 21, 2008
Author(s)
Kirk D. Rice, Michael A. Riley, Amanda L. Forster
This Office of Law Enforcement Standards (OLES) performance standard provides the criteria, requirements, methodology, and procedures for ballistic resistance evaluation of personal body armor, under the jurisdiction of the NIJ Compliance Testing Program

Reaction of Ceiling Tile Systems to Shocks. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5D) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Richard G. Gann, Michael A. Riley, J M. Repp, A S. Whittaker, Andrei Reinhorn, P A. Hough
The degree of damage to the ceiling tile systems of the World Trade Center towers following the aircraft impacts on September 11, 2001, could have affected the rate at which the ensuing fires heated the steel- trussed concrete slab floor systems above

Discussion of Definition of Wind Profiles in ASCE 7 by Yin Zhou and Ahsan Kareem

November 1, 2003
Author(s)
Emil Simiu, Fahim Sadek, Michael A. Riley
The discussion presents a critique of a paper published in the Journal of Structural Engineering, Aug. 2002, pp. 1082-1086. The main points of the discussion are: (1) the ASCE Standard definition of wind profiles is inconsistent with the ASCE definition of

Energy Dissipation Devices for Bridges with Steel Superstructures

April 1, 2003
Author(s)
Michael A. Riley
Recent earthquakes have clearly demonstrated the seismic vulnerability of bridges constructed with steel superstructures. The relative flexibility of these bridges, especially in the transverse direction, may result in overstressing or even failure of

Experimental Testing of Roof to Wall Connections in Wood Frame Houses

April 1, 2003
Author(s)
Michael A. Riley, Fahim H. Sadek
The majority of residential construction in the United States is wood-frame construction. These buildings perform well under gravity loads, but considerable damage has been observed in such structures after significant earthquakes and major hurricanes

Data-Assisted Design for Wind Loading

June 1, 2002
Author(s)
Emil Simiu, Fahim Sadek, T Whalen, S Jang, L L. Lu, S M. Diniz, A Grazini, Michael A. Riley
Current ASCE Standard provisions on wind loads for low-rise building design are based on wind tunnel tests conducted at the University of Western Ontario in the 1970's. In spite of the advances they entailed at the time, those provisions are inadequate

Design Procedures for Structures with Supplemental Dampers

April 1, 2001
Author(s)
Fahim Sadek, Michael A. Riley
Passive energy dissipation devices are used to reduce the damage from earthquakes by absorbing a portion of the earthquake-induced energy in structures. Wide acceptance of these devices in structures will depend on the availability of simplified methods

NIST Research on Structural Performance of Housing Systems

April 1, 2001
Author(s)
Fahim Sadek, Michael A. Riley
An outline of NIST research in the area of structural performance of housing systems is presented in this paper. The performance of wood-frame houses in past earthquakes and hur-ricanes is summarized, and the state-of-the-art in experimental and analytical

Linear Procedures for Structures with Velocity-Dependent Dampers

August 1, 2000
Author(s)
Fahim Sadek, B Mohraz, Michael A. Riley
Passive energy dissipation devices are used to reduce the damaging effects of earthquakes. These devices can absorb a portion of the earthquake-induced energy in structures and thus reduce the energy demand on structural members. Wide acceptance of these

Guidelines for Testing Passive Energy Dissipation Devices

November 1, 1999
Author(s)
Michael A. Riley, Fahim H. Sadek, B Mohraz
Passive energy dissipation devices can be used to significantly reduce the response of structures to earthquake and wind excitation. Wide acceptance of these devices depends on the availability of information on their performance as well as standards for
