Modeling of Bolted Connections for Collapse Analysis of Steel Structures

September 19, 2011
Author(s)
Joseph A. Main, Fahim Sadek
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 sustain

Analytical and Experimental Assessment of Steel Truss Bridge Gusset Plate Connections

Mark A. Iadicola, Yavuz Mentes, Yoon D. Kim, Robert S. Zobel, Donald W. White, Roberto T. Leon, Justin M. Ocel
This paper focuses on findings from comprehensive studies of steel truss bridge gusset plate behavior and proposes practical design procedures. The studies include comparisons of analytical models to responses from large-scale experimental tests from

Optimization and Multi-Hazard Design

July 6, 2009
Author(s)
Emil Simiu, Florian A. Potra
There is a growing interest in the development of procedures for the design of structures exposed to multiple hazards. The goal is to achieve safer and/or more economical designs than would be the case if the structures were analyzed independently for each

Testing and Analysis of Steel Beam-Column Assemblies under Column Removal Scenarios

May 6, 2009
Author(s)
Fahim Sadek, Joseph A. Main, Hai S. Lew, Stephen D. Robert, Vincent Chiarito
This paper presents an experimental and analytical assessment of the performance of steel beam-column assemblies with two types of moment-resisting connections under vertical displacement of a center column, simulating a column removal scenario. The

PERFORMANCE OF SEISMIC MOMENT RESISTING CONNECTIONS UNDER COLUMN REMOVAL SCENARIO

April 9, 2008
Author(s)
Fahim Sadek, Hai S. Lew, Joseph A. Main, John L. Gross
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 collapse
