Numerical modeling of heat transfer in steel-concrete composite slabs

June 10, 2016
Author(s)
Jian Jiang, Joseph A. Main, Jonathan M. Weigand, Fahim Sadek
This paper presents detailed and reduced-order numerical modeling of heat transfer in composite floor slabs with profiled steel decking. The detailed modeling approach represents the concrete slab with solid elements and the steel decking with shell

Temperature-Dependent Material Modeling for Structural Steels: Formulation and Application

April 15, 2016
Author(s)
Mina S. Seif, William E. Luecke, Lisa Y. Choe, Joseph A. Main, Joseph D. McColskey, Chao Zhang, Jonathan M. Weigand, John L. Gross, Fahim Sadek
This report presents the formulation and application of a newly developed temperature-dependent material model for structural steels. First it presents a model for computing the stress-strain behavior of structural steel for conditions appropriate to fire

Finite element modeling of structural steel component failure at elevated temperatures

March 12, 2016
Author(s)
Mina S. Seif, Joseph A. Main, Jonathan M. Weigand, Therese P. McAllister, William E. Luecke
A key issue in evaluating the response of structural systems to fire effects is the representation of material behavior at elevated temperatures. In addition to stress-strain behavior, modeling of fracture is required to capture failure modes such as tear

Integrity of Bolted Angle Connections Subjected to Simulated Column Removal

December 8, 2015
Author(s)
Jonathan M. Weigand, Jeffrey W. Berman
Large-scale tests of steel gravity framing systems (SGFSs), one of the most commonly used structural systems in the United States, have shown that enhancements may be required to achieve the desired levels of integrity to collapse when a column suffers

Analysis of a Half-Scale Composite Floor System Test under Column Loss Scenarios

April 23, 2015
Author(s)
Joseph A. Main, Jonathan M. Weigand, Eric S. Johnson, Tim Francicso, Judy Liu, Jeffrey W. Berman, Larry A. Fahnestock
This paper describes modeling and analysis of a half-scale steel gravity frame system with composite concrete slab on steel deck that was constructed and tested at the University of Illinois under corner, edge, and interior column removal scenarios. For

New Steel Gravity Connection Details for Enhanced Integrity

April 23, 2015
Author(s)
Jonathan M. Weigand, Jeffrey W. Berman
Recent large-scale tests have found that Steel Gravity Framing Systems (SGFSs) with conventional connections were inadequate to support the integrity gravity load combinations under column removal scenarios. To address this issue, detailed connection
