Fragility analysis of steel MRFs: Effects of frequency-content components of near-fault pulse-like ground motions and setbacks

Vibration control of steel frames with setback irregularities equipped with semi-active tuned mass dampers

“…The mass, stiffness, and strength distribution in the horizontal and vertical plans of a structure have significant effects on its seismic response under strong ground motions [28][29][30]. Irregularities such as structures with setbacks exhibit undesirable seismic behavior under strong earthquakes [31,32]. Several investigations on the inelastic seismic response of structures with setbacks indicate that, compared to regular frames, there was a noticeable change in the seismic response of frames with setbacks [31].…”

“…The seismic performance of structures with setbacks under pulse-like events was numerically studied by Mashhadi et al [32,37]. The results show that the seismic behavior of structures with setbacks depends on the ratio of the pulse period to the structures' first mode period, (T P /T 1 ).…”

Seismic Fragility Assessment of SMRFs Equipped with TMD Considering Cyclic Deterioration of Members and Nonlinear Geometry

“…They examined the effect of site condition, aftershock intensity, seismic wall area ratio, reinforced concrete tie column, number of stories, and mortar strength. A study conducted by Mashadi et al [30] examined the impact of forward directivity pulses as well as the high-frequency components of near-fault earthquake records on the seismic performance of regular and irregular structures using fragility curves. The seismic fragility curves were also used by Borhan et al [31] to investigate the performance of rotational-friction slip dampers in steel structures of varying heights.…”
