Predominant Frequency in Near-Field Strong Ground Motion by Analysis of Displacement Response Spectra

Buildings, 2023
A literature review on the spectral content of seismic ground motion indicates that a clear predominant frequency in earthquakes is very difficult to define.

Performance of base-isolated moment resisting steel frames subjected to pounding effects under near-field earthquake ground motions [PDF]

Journal of Structural and Construction Engineering, 2021
Despite conservative requirements of existing building code regarding clear seismic gap distance of base-isolated (BI) structures to surrounding moat walls, seismic performance of these structures is still ambiguous under severe earthquake ground motions

Near-Collapse Probability of RC Frames in Indonesia Under Repeated Earthquakes Containing Fling-Step Effect

International Journal of Technology, 2023
The velocity pulse and displacement fling-step pulse signatures may be present in a near-field earthquake ground motion record. It is generally known that near-field ground motion with pulse effects accelerated the building drift.

Laser Cooling of an Optomechanical Crystal Resonator to Its Quantum Ground State of Motion [PDF]

, 2012
Quantum mechanics continues to intrigue us with bizarre predictions that seemingly run counter to our everyday classical intuition. Superposition, zero-point motion, entanglement, and inescapable bounds on measurement precision are just a few purely ...

Ground-motion predictive equations for low-magnitude earthquakes in the Campania–Lucania area, Southern Italy

, 2010
A key aspect of ground-shaking map calculation is represented by ground-motion predictive equations (GMPEs). In fact, ground-shaking maps obtained soon after an earthquake are calculated by integrating observed data and ground-motion estimates from GMPEs

Interlayer Isolation Structures Considering Soil–Structure Interaction under Long-Period Ground Motions: An Experimental Analysis

Applied Sciences, 2023
After coupling long-period seismic motions with the soil–structure interaction (SSI) effect, isolated structures can easily be resonated, and the seismic response of the structure is significantly enhanced.

Evaluation of ground motion parameters and seismic response of reinforced concrete buildings from the Mw 6.9, 2011 Sikkim earthquake

Geohazard Mechanics, 2023
The continuous collision of the Eurasian plate and the Indian plate has resulted in several earthquakes in the Himalayan region. The 6.9 Mw 2011 Sikkim earthquake, which caused immense damage to the built environment in Sikkim, was triggered by an ...

Spectral element method simulation of three-dimensional sedimentary basin under reverse-fault earthquakes

地震科学进展, 2020
Near-fault ground motion can cause serious earthquake disaster in the near-field area，especially when there is sedimentary topography in the area. At present，there are no reports on the ground motion response of sedimentary basins under the action of ...
