Influence of Gravity Framing on the Collapse Probability of Steel Buildings with Special Moment Frames

This paper presents the influence of gravity framing on collapse risk steel frame buildings with perimeter special moment frames (SMFs) designed in Turkey. For this, four- and eight-story have been considering related current specifications codes. Header end-plate connections are used for beam-to-column joints system. A nonlinear analytical model that simulates hysteretic behavior header is calibrated past experimental data. Nonlinear static pushover analysis (NSPA) response history analyses (NRHAs) were implemented both four-story SMFs without to quantify their performance monitor system-level seismic building through collapse. The advantage presence investigated differences structural responses between models also examined. When excited by different ground motions, median detailed showed an increase lateral force carrying capacity a decrease first-story drift demand, compared results. Furthermore, results demonstrate structure profoundly possibility
