41. Modeling of Bolted Connections for Collapse Analysis of Steel Structures
Published: 9/19/2011
Authors: Joseph A Main, Fahim Sadek
Abstract: In structural collapse scenarios, beam to column connections can be subjected to large rotations as the structure deforms, in addition to large axial forces associated with the development of catenary action. The capability of the connections to sust ...

42. Modeling of Double-Angle Shear Connections for Evaluation of Structural Robustness
Published: 10/31/2012
Authors: Judy Liu, Joseph A Main, Fahim Sadek
Abstract: Improved structural robustness is expected for steel gravity load-resisting frames with double-angle shear connections as compared to single-plate connections, given the larger deformation capacity of the double angle. Detailed models of bolted doubl ...

43. NIST Research on Structural Performance of Housing Systems
Published: 4/1/2001
Authors: Fahim Sadek, Michael A Riley
Abstract: 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 ana ...

44. Overview of the Structural Design of World Trade Center 1, 2, and 7
Published: 9/1/2012
Authors: Therese P McAllister, Fahim Sadek, John L Gross, Jason D Averill, Richard George Gann
Abstract: This paper summarizes the primary structural systems which comprised World Trade Center 1, World Trade Center 2, and World Trade Center 7. The buildings were destroyed in the terrorist attacks of September 11, 2001. This paper describes the four ma ...

45. PERFORMANCE OF SEISMIC MOMENT RESISTING CONNECTIONS UNDER COLUMN REMOVAL SCENARIO
Published: 4/9/2008
Authors: Fahim Sadek, Hai Sang Lew, Joseph A Main, John L Gross
Abstract: Beam-to-column moment connections in steel frame construction have been studied extensively for seismic applications.  However, the behavior of such connections has not been studied under the monotonic loading conditions expected in progressive ...

46. Peak Non-Gaussian Wind Effects for Data Base-Assisted Low-Rise Building Design
Published: 5/1/2002
Authors: Fahim Sadek, Emil Simiu
Abstract: Current procedures for estimating the peaks of the stochastic response of tall buildings to wind are based on the assumption that the response is Gaussian. Those procedures are therefore inapplicable to low-rise buildings, in which time histories of ...

47. Performance of Physical Structures in Hurricane Katrina and Hurricane Rita: A Reconnaissance Report (NIST TN 1476)
Series: Technical Note (NIST TN)
Report Number: 1476
Published: 6/30/2006
Authors: Stephen A Cauffman, Long Thanh Phan, Fahim Sadek, William P. Fritz, Dat Duthinh, Walter J. Rossiter
Abstract: This is the final report on the National Institute of Standards and Technology (NIST) led-reconnaissance to assess the performance of physical structures during Hurricane Katrina and Hurricane Rita. The report describes the environmental conditions ( ...

48. Performance of Steel Moment Connections under a Column Removal Scenario. I: Experiments
Published: 4/3/2012
Authors: Hai Sang Lew, Joseph A Main, Stephen D Robert, Fahim Sadek, Vincent Chiarito
Abstract: This paper presents an experimental study of two full-scale steel beam-column assemblies, each comprising three columns and two beams, to (1) define their response characteristics under a column removal scenario, including the capacity of the beams a ...

49. Performance of Steel Moment Connections under a Column Removal Scenario. II: Analysis
Published: 4/3/2012
Authors: Fahim Sadek, Joseph A Main, Hai Sang Lew, Sherif El-Tawil
Abstract: This paper presents a computational investigation of the response of steel beam-column assemblies with moment connections under monotonic loading conditions simulating a column removal scenario. Two beam-column assemblies are analyzed, which incorpo ...

50. Robustness of Composite Floor Systems With Shear Connections: Modeling, Simulation, and Evaluation
Published: Date unknown
Authors: Fahim Sadek, Sherif El-Tawil, Hai Sang Lew
Abstract: This paper presents an analytical assessment of the robustness of concrete deck-steel beam composite floor systems with shear connectors under the assumption that an interior column has been removed. The study provides an insight into the behavior a ...
