Seismic Performance of Midstory Isolated Structures under Near-Field Pulse-Like Ground Motion and Limiting Deformation of Isolation Layers [PDF]

Shock and Vibration, 2015
Excessive deformation of the isolation layer in midstory isolated structures may occur under strong near-field pulse-like ground motion, which would result in the overturning collapse of the superstructure.

Near-Earth substorm features from multiple satellite observations [PDF]

, 2008
We investigate a substorm on 3 October 2004 during which 11 satellites were located in near-Earth magnetotail (XGSM > −10 RE). Double Star 1 (TC-1), Cluster, and LANL-97 satellites were closely aligned in the dawn-dusk direction (

Interplanetary magnetic field rotations followed from L1 to the ground : the response of the Earth's magnetosphere as seen by multi-spacecraft and ground-based observations [PDF]

, 2011
A study of the interaction of solar wind magnetic field rotations with the Earth's magnetosphere is performed. For this event there is, for the first time, a full coverage over the dayside magnetosphere with multiple (multi)spacecraft missions from dawn ...

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 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

Study on the shock-absorbing effect of a new staggered story isolated structure under the long-period earthquake motion

Frontiers in Earth Science, 2023
The finite element model of a new staggered story isolated structure is established. Using the time-history analysis method, the dynamic response state of the structure at each time step is calculated by integrating the acceleration time-history data ...

Time evolution of ground motion-dependent depolarisation at linear colliders [PDF]

, 2009
Future linear colliders plan to collide polarised beams and the planned physics reach requires knowledge of the state of polarisation as precisely as possible. The polarised beams can undergo depolarisation due to various mechanisms. In order to quantify

Research progress of baseline correction for near-field strong motion accelerogram

地球与行星物理论评, 2022
The baseline drift is often found in strong motion accelerograms, especially in the near-field accelerogram. The small baseline drift in accelerogram will lead to linear drift in the velocity time history obtained through single integration and parabolic
