11. 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 ...

12. 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 ...

15. 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 ...

16. Testing and Analysis of Steel and Concrete Beam-Column Assemblies under a Column Removal Scenario
Published: 9/1/2011
Authors: Fahim Sadek, Joseph A Main, Hai Sang Lew, Yihai Bao
Abstract: This paper presents an experimental and computational assessment of the performance of steel and reinforced concrete beam-column assemblies under vertical displacement of a center column, simulating a column removal scenario. The assemblies represent ...
