An isolation device for near-fault ground motions
Structural Control and Health Monitoring, 2013 Seismic isolation is an appreciable control strategy that reduces the vibrations of structural and nonstructural systems induced by strong ground motions. However, under near-fault (NF) ground motion, the seismic isolation devices might perform poorly because of large isolator displacements caused by long-period large velocity and displacement pulses ...

Investigation of Uplift force effects on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions:Case Study Shafaroud Dam [PDF]
Journal of Structural and Construction Engineering, 2019 Uplift force has significant role on dynamic response of concrete gravity dams and also seismic response of dams in near field motion can be considerably different from those observed in the far field and the near –fault ground motions can cause ...

Seismic Energy Response of SDOF Systems Subjected to Long-Period Ground Motion Records
Advances in Civil Engineering, 2021 To provide an important reference for the energy-based seismic design of long-period structures, the elastoplastic dynamic analysis program is employed to study the seismic energy response of single-degree-of-freedom (SDOF) systems under two types of ...

Dimensional response analysis of bilinear systems subjected to non-pulselike earthquake ground motions [PDF]
, 2011 The maximum inelastic response of bilinear single-degree-of-freedom systems when subjected to ground motions without distinguishable pulses is revisited with dimensional analysis by identifying time scales and length scales in the time histories of ...

Dimensional response analysis of multistorey regular steel MRF subjected to pulselike earthquake ground motions [PDF]
, 2010 An alternative and efficient procedure to estimate the maximum inelastic roof displacement and the maximum inelastic interstorey drift ratio along the height of regular multi-storey steel MRF subjected to pulse-like ground motions is proposed. The method

Assessment of Near-Fault Ground Motion Effects on the Fragility Curves of Tall Steel Moment Resisting Frames [PDF]
Civil Engineering Infrastructures Journal, 2020 Nowadays it is common to use the fragility curves in probabilistic methods to determine the collapse probability resulting from an earthquake. The uncertainties exist in intensity and frequency content of the earthquake records are considered as the most

Frontiers in Built Environment, 2016 The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements
