Abstract
Mid-America region is defined as the region of the central and southeastern United States compromising those states that have expected large but infrequent seismicity. Although earthquakes in this region are less frequent than in western U.S., they affect much larger areas than those of similar magnitude in western U.S. due to the deep and loose subsurface conditions. However, as little research has been carried out for partially restrained (PR) steel moment frame structures in this region, it is necessary to evaluate their seismic performance. To achieve this, seismic performance of three proto-type 6-story steel moment frames with T-stub PR connections was evaluated in accordance with FEMA 273/356 limit state criteria using fragility analyses. Three PR frames were designed using the appropriate design codes representing mid-1950s, late 1980s, and current practice. Two different types (“Conventional” and “New”) of fragility curves are developed and compared. In addition, the fragility curves at Los Angeles site representing western U.S. were generated and compared with those at the Mid-America region. Two different fragility analysis results show the same trends. Three proto-type 6 story PR frames in the Mid-America earthquake region performed well and may not collapse. It can be concluded that the seismic performance of the mid-rise PR frames in the Mid-America region will be satisfactory even under large but infrequent ground motions.
