“…Detailed three-dimensional (3D) finite element models, therefore, would be more appropriate to analyze the test, and they were used by Tada et al [7], Pan et al [8], Miyamura et al [9], and Isobe et al [10]. However, those simulations required large modeling and computational efforts, not really necessary for the most of structural components responding elastically or even inelastically as long as simpler analytical techniques are available.…”

Summary This paper presents three‐dimensional nonlinear dynamic analyses of a full‐scale four‐story steel building tested to collapse in 2007 at the E‐Defense shake‐table facility in Japan, using strong ground motion. Local buckling and consequent strength deterioration of all six columns at the first‐story level were observed as the main reason for the building collapse. Fiber hinge element that consists of fibers discretizing the column cross section is used model each end of the column. It has zero length but considers finite yield‐zone length for the fiber to simulate elastoplastic behavior and local buckling. Other parts of the building are modeled by standard column, beam, truss, and spring elements. Despite the unavoidable limitation of the parameters defining the fiber hinge element's properties that are empirically determined from the behavior of the cantilever column tested using an identical steel member, the analysis using the element appears to simulate well the column behavior because of the axial load and biaxial bending moment whose relative magnitudes differ considerably because of the locations. The analysis results indicate different deterioration patterns of the columns and effects of complex loading such as compression and tensile axial load applied alternately, additional high frequency axial load caused by vertical accelerations, and shifting of the principal directions of the bending moments cycle by cycle. Responses such as story drift, accelerations, base shear, and energy dissipation are also simulated well, and progress of local deterioration in the first‐story columns and global soft‐story mechanism is clarified by the analysis.

“…Numerical simulations using 2D frame models have been conducted for steel frames, and these simulations still have important roles in designing and analyzing building frames [12][13][14][15]. Recently, 3D frame models [16][17][18][19][20][21][22][23] have been widely used. These models are classified as concentrated models, in which inelasticity is concentrated at the ends of a member, and distributed models, in which inelasticity is distributed along the length of the member.…”

Dynamic finite element analyses of a four-story steel building frame modeled as a fine mesh of solid elements are performed using E-Simulator, which is a parallel finite element analysis software package for precisely simulating collapse behaviors of civil and building structures. E-Simulator is under development at the National Research Institute for Earth Science and Disaster Prevention (NIED), Japan. A full-scale shake-table test for a four-story frame was conducted using E-Defense at NIED, which is the largest shaking table in the world. A mesh of the entire structure of a four-story frame with approximately 19 million degrees of freedom is constructed using solid elements. The density of the mesh is determined by referring to the results of elastic-plastic buckling analyses of a column of the frame using meshes of different densities. Therefore, the analysis model of the frame is well verified. Seismic response analyses under 60, 100, and 115% excitations of the JR Takatori record of the 1995 Hyogoken-Nanbu earthquake are performed. Note that the simulation does not reproduce the collapse under the 100% excitation of the Takatori record in the E-Defense test. Therefore, simulations for the 115% case are also performed. The results obtained by E-Simulator are compared with those obtained by the E-Defense full-scale test in order to validate the results obtained by E-Simulator. The shear forces and interstory drift angles of the first story obtained by the simulation and the test are in good agreement. Both the response of the entire frame and the local deformation as a result of elastic-plastic buckling are simulated simultaneously using E-Simulator.The main core of E-Simulator is the commercial software package ADVENTURECluster [4][5][6][7], which has been extended from the open-source version, the ADVENTURE system [8,9]. These packages use FE SIMULATION OF FOUR-STORY STEEL FRAME MODELED BY SOLID ELEMENTS

“…The authors simulated the test of the 4-story steel frame using the ESimulator [3]. Isobe et al [8] performed analyses of the frame using an adaptive finite element code, the ASI-Gauss code, which is based on the beam element. They compared the results with those obtained by the E-Simulator [3] and the experimental results of the E-Defense test.…”
