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
