Investigation of Sediment in the reservoir on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions [PDF]
Journal of Structural and Construction Engineering, 2020 Sediment in the dam’s reservoir has a significant role on mitigation of dynamic response of concrete gravity dams and also the seismic response of dams in near-field motion can be considerably different from those observed in the far field and the near ...

Seismic performance of moment frames under multiple fling-step pulse ground motions
Jurnal Ilmiah SINERGI, 2022 The displacement fling-step pulse seldom signatures near-field earthquake in its ground motions. It is well recognized that the near-field ground motion with velocity pulse amplifies the building drift larger than the regular ground motion.

Seismic performance of frame‐bent structures subjected to near‐fault ground motions
The Journal of Engineering, 2021 Reinforced concrete frame‐bent structures are one of the structural forms commonly used in industrial factory buildings. In order to study the seismic behaviour of frame‐bent structures located near fault areas, eight pulse‐like, eight non‐pulse near ...

Near-field horizontal and vertical earthquake ground motions [PDF]
Soil Dynamics and Earthquake Engineering, 2003 Strong-motion attenuation relationships are presented for peak ground acceleration, spectral acceleration, energy density, maximum absolute input energy for horizontal and vertical directions and for the ratio of vertical to horizontal of these ground motion parameters. These equations were derived using a worldwide dataset of 186 strong-motion records
