11. An Experimental and Computational Study of Reinforced Concrete Assemblies under a Column Removal Scenario
Series: Technical Note (NIST TN)
Report Number: 1720
Published: 10/26/2011
Authors: Hai Sang Lew, Yihai Bao, Fahim Sadek, Joseph A Main, Santiago Pujol, Mete Sozen
Abstract: This report presents an experimental and computational study of two reinforced concrete beam-column assemblies, each comprising three columns and two beams. The two beam-column assemblies represent portions of the structural framing system of two ten ...

12. 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 ...

13. 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 ...

18. Assessment of Robustness and Disproportionate Collapse Vulnerability of Steel Moment-Frame Buildings
Published: 8/19/2009
Authors: Joseph A Main, Fahim Sadek, Hai Sang Lew
Abstract: Several prototype steel moment-frame buildings have been designed for the purpose of assessing their vulnerability to progressive collapse. The buildings were designed for moderate and high seismic regions. This paper summarizes the development of th ...
