P-Delta Effect on Residual Displacement and Collapse Capacity of SDOF Systems during Long and Short Duration Earthquakes [PDF]

پژوهش‌های زیرساخت‌های عمرانی, 2022
In structural analysis, P-Delta effect refers to the changes in internal forces due to P-Delta moment which can be found by multiplying gravity load (P) by the lateral displacement of structure for earthquake lateral load (Delta).

Earthquake response prediction of seismically isolated buildings based on the response spectrum method considering changes in characteristics of lead rubber bearings due to repeated deformations

Japan Architectural Review, 2023
In 2016, a countermeasure was announced against the Nankai Trough long‐period and long‐duration ground motions (LPGMs) in Japan. However, the response spectrum method (RSM), indicated by the Ministry of Construction notification Vol.

An Early Forecast of Long‐Period Ground Motions of Large Earthquakes Based on Deep Learning

Geophysical Research Letters, 2023
Long‐period (LP; approximately 2–10 s) ground motions generated by large earthquakes are amplified in large basins and threaten high‐rise buildings in modern cities.

Critical Response of Multi-Story Damped Bilinear Hysteretic Shear Building Under Multi Impulse as Representative of Long-Period, Long-Duration Earthquake Ground Motions

Frontiers in Built Environment, 2020
The critical response is investigated for a multi-story damped bilinear hysteretic shear building model under a multi impulse as a representative of long-period, long-duration earthquake ground motions. The critical response for an elastic–plastic single-

The spatial properties of the site amplifications of S-waves by generalized spectral inversion technique and the correction method of the site amplifications considering the contribution of later arrivals after major S-waves

Earth, Planets and Space, 2023
Site amplification is an important component of strong ground motion prediction as it differs among sites, reflecting its specific local subsurface geology.

Effectiveness of modified pushover analysis procedure for the estimation of seismic demands of buildings subjected to near-fault ground motions having fling step [PDF]

Natural Hazards and Earth System Sciences, 2013
Near-fault ground motions with long-period pulses have been identified as being critical in the design of structures. These motions, which have caused severe damage in recent disastrous earthquakes, are characterized by a short-duration impulsive motion ...

Uncertainties in long-period ground motion and its impact on building structural design: Case study of the 2011 Tohoku (Japan) earthquake [PDF]

, 2013
On March 11, 2011, Japan was shaken by the 2011 off the Pacific coast of Tohoku earthquake (the Great East Japan Earthquake). This paper reports some aspects of this earthquake related to long-period ground motions and its impact on building structural ...

Automatic generation of smart earthquake-resistant building system: Hybrid system of base-isolation and building-connection

Heliyon, 2016
A base-isolated building may sometimes exhibit an undesirable large response to a long-duration, long-period earthquake ground motion and a connected building system without base-isolation may show a large response to a near-fault (rather high-frequency)

Windsock memory conditioned RAM (Co-Ram) pressure effect: forced reconnection in the Earth's magnetotail [PDF]

, 2014
Magnetic reconnection (MR) is a key physical concept explaining the addition of magnetic flux to the magnetotail and closed flux lines back-motion to the dayside magnetosphere. This scenario elaborated by \citet{dung63}, can explain many aspects of solar
