51. Robustness of Steel Gravity Frame Systems with Single-Plate Shear Connections
Series: Technical Note (NIST TN)
Report Number: 1749
Published: 2/27/2013
Authors: Joseph A Main, Fahim H Sadek
Abstract: This report presents a computational assessment of the performance of steel gravity framing systems with single-plate shear (“shear tab”) connections and composite floor slabs under column loss scenarios. The computational assessment uses a reduced m ...

52. Sampling Errors in the Estimation of Peak Wind-Induced Internal Forces in Low-Rise Structures
Published: 2/1/2004
Authors: Fahim H Sadek, S M Diniz, M Kasperski, M Gioffre, Emil Simiu
Abstract: Peak values in time histories of wind effects may be obtained by using the entire information inherent in the time series of the wind effect, a method entailing the estimation of the probability distribution of the peak through the application of the ...

53. Semi-Active Control of Linear and Hysteretic Structures Using Variable Viscous and Magnetorheological Dampers
Published: 7/1/2000
Authors: S El-Borgi, Michael A Riley, Fahim H Sadek, N Ayed
Abstract: Numerous studies have been conducted so far on active or hybrid (active/passive) control of hysteretic structures using a wide range of linear and nonlinear control algorithms. However, most research work on the use of semi-active control systems has ...

54. Stochastic Linearization for Control of Hysteretic Structures Using H(Infinity) Algorithm
Published: 1/1/2001
Authors: M Ben Ftima, Fahim H Sadek, S El-Borgi, Michael A Riley
Abstract: This paper presents a robust static output feedback H(infinity) algorithm for control of hysteretic civil engineering structures subjected to earthquake ground motions. Hysteretic structures present a problem for control design and algorithm develop ...

55. Strength Evaluation of Connectors for Intermodal Containers
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6557
Published: 8/1/2000
Authors: Hai Sang Lew, Fahim H Sadek, E D Anderson
Abstract: 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 ...

59. Structural Reliability Estimates and Database-Assisted Design for Wind
Published: 6/1/2002
Authors: F Minciarelli, Fahim H Sadek, Emil Simiu, Mircea Grigoriu
Abstract: 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 indic ...
