Wind Speeds in ASCE 7 Standard Peak-Gust Map: Assessment

April 1, 2003
Author(s)
Emil Simiu, R Wilcox, Fahim Sadek, James J. Filliben
The ASCE 7 peak-gust map division of the conterminous United States into two adjacent wind speed zones does not reflect correctly the country's differentiated extreme wind climate. The methodology used to develop the map averages out real climatological

Wind Speeds in the ASCE 7 Standard Peak-Gust Map: An Assessment

Distribution of Earthquake Input Energy in Structures

January 1, 2003
Author(s)
P Khashaee, B Mohraz, Fahim H. Sadek, Hai S. Lew, John L. Gross
In developing an energy-based design approach and assessing the damage potential of structures, one must know the distribution of earthquake input energy among energy components: kinetic, elastic strain, hysteretic, and damping. This report examines the

Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames

December 1, 2002
Author(s)
S Jang, L L. Lu, Fahim H. Sadek, Emil Simiu
A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns (magnitude and distribution) established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7

Database-Assisted Design for Wind: Basic Concepts and Software Development

November 1, 2002
Author(s)
T Whalen, Fahim H. Sadek, Emil Simiu
Standard provisions for wind loads on buildings have traditionally been based on summary tables and/or plots suitable for slide-rule calculations. The accuracy in the definition of wind loads inherent in such tables and plots is far lower than that

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

Structural Reliability Estimates and Database-Assisted Design for Wind

June 1, 2002
Author(s)
F Minciarelli, Fahim H. Sadek, Emil Simiu, Mircea Grigoriu
We propose a probabilistic methodology for developing improved estimates of extreme wind effects and load factors in standard provisions for wind loads. We obtained the following results: (1) the discrepancy between current estimates of safety indices for

Ultimate Capacities of Low-Rise Steel Frames in Turbulent Wind

July 1, 2001
Author(s)
S Jang, L L. Lu, Fahim H. Sadek, Emil Simiu
This paper is a derivative of G2001-1392, Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames, by Jang, S., et al., intended for publication in the Journal of Structural Engineering.The original paper's abstract was:A comparative study

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

Strength Evaluation of Connectors for Intermodal Containers

August 1, 2000
Author(s)
Hai S. Lew, Fahim Sadek, E D. Anderson
Intermodal containers are used widely in marine cargo handling. In order to facilitate unloading of empty containers from ship to shore, two containers are lifted frequently in tandem. This operation is referred to as vertical tandem lifting. In this

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

Summary of the Structural Performance of Single-Family, Wood-Frame Housing

September 1, 1998
Author(s)
Charles W. Yancey, Geraldine Cheok, Fahim H. Sadek, B Mohraz
A review of the structural performance of single-family, wood-frame houses is presented. The performance of these structures in selected earthquakes and hurricanes is summarized. In general, wood-frame houses performed well with relatively few instances of
