11. Modeling of Bolted Connections for Collapse Analysis of Steel Structures
Published: 9/19/2011
Authors: Joseph A Main, Fahim H 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 ...

12. Testing and Analysis of Steel and Concrete Beam-Column Assemblies under a Column Removal Scenario
Published: 9/1/2011
Authors: Fahim H 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 ...
