Large-Scale Cyclic and Hybrid Simulation Testing and Development of a Controlled-Rocking Steel Building System with Replaceable Fuses Eatherton, Matthew R.; Hajjar, Jerome F. (Newmark Structural Engineering Laboratory. University of Illinois at Urbana-Champaign., 2010-09)Current U.S. building codes and earthquake engineering practice utilize inelasticity in the seismic force resisting system to dissipate seismic energy and protect against collapse. Inelasticity in conventional structures ...
Nonlinear behavior of controlled rocking steel-framed building systems with replaceable energy dissipating fuses Hall, Kerry S.; Eatherton, Matthew R.; Hajjar, Jerome F. (Newmark Structural Engineering Laboratory. University of Illinois at Urbana-Champaign., 2010-10)This report summarizes the results of a parametric study of a controlled rocking seismic lateral resistance system that includes two steel braced frames linked by replaceable energy dissipating fuses that are engaged by ...
Denavit, Mark D.; Hajjar, Jerome F. (Newmark Structural Engineering Laboratory. University of Illinois at Urbana-Champaign., 2010-03)Accurate nonlinear formulations are necessary for the assessment of structures under seismic and other extreme loading. In this work, a three-dimensional distributed plasticity beam element formulation for circular ...
LaFave, James; Fahnestock, Larry; Foutch, D.A.; Steelman, Joshua; Revell, Jessica; Filipov, Evgueni; Hajjar, Jerome F. (2013-06)The Illinois Department of Transportation (IDOT) commonly uses elastomeric bearings to accommodate thermal deformations in bridges, and these bearings have potential utility in seismic events. IDOT has developed an ...
A Synopsis of Studies of the Monotonic and Cyclic Behavior of Concrete-Filled Steel Tube Members, Connections, and Frames Gourley, Brett C.; Tort, Cenk; Denavit, Mark D.; Schiller, Paul H.; Hajjar, Jerome F. (Newmark Structural Engineering Laboratory. University of Illinois at Urbana-Champaign., 2008-04)A significant amount of research has been conducted worldwide on the behavior of concrete filled steel tubes (CFTs) in the past five decades. This report provides a summary of the behavior and experimental work of concrete ...
Steelman, Joshua; Hajjar, Jerome F. (2008-09)The Mid-America Earthquake (MAE) Center has performed much research since its inception relating to all facets of seismic loss assessment and risk management, from hazard definition through social and economic loss modeling. ...
