34. Modeling and Analysis of Disproportionate Collapse of RC Structures
Published: 10/31/2011
Authors: Yihai Bao, Hai Sang Lew, S K. Kunnath
Abstract: Collapse analyses of a 10-story reinforced concrete frame building are carried out to investigate the robustness of structural systems against column removal scenarios. Computationally efficient reduced models are developed and used in the analyses. ...

36. 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 ...
