“…The main conclusion is that tubular steel beam-columns deteriorate rapidly for depth (D) to thickness (t) ratios D/t > 30 and high axial load ratios N/N y > 0.3. This was confirmed by a full-scale collapse test of a 4-story steel structure conducted at the E-Defense facility in Japan (Suita et al, 2008). The structure collapsed in a first story mechanism due to column bending strength deterioration caused by local buckling.…”

“…However, in this model the postcapping strength deterioration was not modeled. It has been shown both analytically Zareian and Krawinkler, 2007;Lignos and Krawinkler, 2009) and experimentally (Lignos et al, 2010(Lignos et al, , 2011dSuita et al, 2008) that the capping point is critical for assessing the collapse potential of moment resisting frames Lignos and Krawinkler, 2009;Lignos et al, 2011a). Lee and Foutch (2002a) concluded that all of the buildings with postNorthridge connections showed a high capacity-to-demand ratio ranging from 2.0 to 4.0, depending on frame configuration and height.…”

“…Nakashima and Sawaizumi (2000) suggested that column strength should be greater than 120% of the beam plastic moment capacity, M p , to account for strain-hardening and to control the effects of concentration of plastic deformation. Recently, a fullscale collapse test of a four-story steel frame structure designed based on current Japanese seismic provisions was conducted at the E-Defense shaking table in Japan (Suita et al, 2008). The test structure collapsed in a first-story sidesway mechanism because of increased beam strength due to strain hardening, slab effects, and material variability.…”

“…For steel beams, emphasis will be placed on research that includes beams with reduced beam sections (RBS), welded unreinforced flange-welded (WUF-W) and bolted flange plate (BFP) connections. It is also essential that component simulation models be validated with recent small-scale and full-scale shake table tests (Suita et al, 2008;Lignos et al, 2011a;Lignos et al, 2011d).…”

The objective of this task was to develop a comprehensive long-range plan to research the seismic behavior of deep, slender wide flange structural steel beamcolumns in steel frames. Development of the plan included the investigation of available information on beam-column member and connection behavior in the literature, and considered the differences and interrelationships between member, subassemblage, and system performance. The resulting plan includes a summary of tasks for conducting both experimental and analytical research, and is intended to be the first step in the development of national consensus guidelines for designing and assessing the seismic performance of deep, slender wide-flange beam-columns in steel frame systems.The NEHRP Consultants Joint Venture is indebted to the leadership of Jim Malley, Project Director, and to the members of the Project Technical Committee, consisting of Charlie Carter, Jerry Hajjar, Dimitrios Lignos, Charles Roeder, and Mark Saunders for their contributions in developing this report and the resulting recommendations.

Mork for ATC report production services. Jon A. Heintz Program ManagerGCR 11-917-13 List of Tables Executive SummaryCurrent practice in modern steel frame design frequently concentrates seismic resistance into a few frames or a few bays within planar frames. In moment resisting frames, this practice results in column designs that are dominated by a combination of axial force and bending due to lateral deformation, rather than just axial force alone. Due to their increased in-plane flexural stiffness, deeper column sections are generally selected to satisfy drift criteria and to balance relative stiffness with deep beam sections. Columns that are generally stocky, in terms of both member stability and cross-sectional compactness requirements, are expected to perform well under seismic loading. Deeper, more slender columns, however, are more vulnerable to weak-axis and local buckling failure modes, and these sections must be checked against the potential for in-plane and out-of-plane instability under combined axial load and bending moment.The term deep refers to member depths that are nominally greater than 16 inches (i.e., W16 sections and larger). The term slender refers to members that are sensitive to instability or have cross-sectional elements with width-to-thickness ratios approaching the seismic compactness limits for highly ductile members. An area of critical need identified by the American Institute of Steel Construction (AISC) is the seismic performance of deep, slender, wide flange structural steel beam-column members when subjected to a range of axial loads. Research on the stability of th...

SUMMARYA research program is summarized in which collapse of a steel frame structure is predicted numerically and the accuracy of prediction is validated experimentally through earthquake simulator tests of two 1:8 scale models of a 4-story code-compliant prototype moment-resisting frame. We demonstrate that (1) sidesway collapse can occur for realistic combinations of structural framing and earthquake ground motion; (2) P − effects and component deterioration dominate behavior of the frame near collapse; (3) prediction of collapse is feasible using relatively simple analytical models provided that component deterioration is adequately represented in the analytical model; and (4) response of the framing system near collapse is sensitive to the history that every important component of the frames experiences, implying that symmetric cyclic loading histories that are routinely used to test components provide insufficient information for modeling deterioration near collapse.
