'Structural Model Description': 'This building is located in Woodland Hills, within five miles of the epicenter of the 1994 Northridge earthquake. The east, west, and south moment frames lie on the perimeter of the building, while the north frame is located one bay inside of the perimeter. This gives rise to some torsional eccentricity. Many moment-frame beam-column connections in the building fractured during the Northridge earthquake, and the building has been extensively investigated since then by many engineering research groups (SAC 1995b, Carlson 1999). Detailed floor plans, beam and column sizes, and gravity, wind, and seismic loading criteria are given in Krishnan et al. 2005. A36 steel with nominal yield strength of 248.29 MPa, (36 ksi) is used for all beams, while A572 Grade 50 steel with nominal yield strength of 344.85 MPa (50 ksi) is used for all columns. The floors consist of lightweight concrete slab on metal deck supported by steel beams and girders framing into gravity and moment-frame columns. The model includes a probabilistic distribution to describe the fracture strain for fibers in the bottom-flanges of the moment frame beams.\n',
