Correlation between Pulse-Like Ground Motion Intensity Measures and Seismic Demands of Buildings with Three Structural Systems (Moment-Resisting Frames, Structural Walls and Combination of Moment-Resisting Frames and Shear Walls) [PDF]

Journal of Rehabilitation in Civil Engineering, 2021
In this study, the distribution of correlation coefficients between maximum interstory drift ratio (MIDR) of multistorey building structures and ground motion characteristics intensity measures (IMs) is evaluated and compared.

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 ...

Long-period ground motion simulation using centroid moment tensor inversion solutions based on the regional three-dimensional model in the Kanto region, Japan

Earth, Planets and Space, 2021
We conducted centroid moment tensor (CMT) inversions of moderate (Mw 4.5–6.5) earthquakes in the Kanto region, Japan, using a local three-dimensional (3D) model.

Proposition of isolation system applicable to the long-period earthquake ground motion (Method of changing natural frequency of isolation system with additional spring)

Nihon Kikai Gakkai ronbunshu, 2019
At present, there are many types of isolation system, and many of them are designed for the short-period ground motion. The long-period ground motion has recently attracted the attention, though the isolation system for the short-period ground motion ...

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 ...

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.

Simulation of long-period ground motion near a large earthquake [PDF]

Bulletin of the Seismological Society of America, 1997
AbstractWe estimated the possible range of long-period ground motion for sites located on a soft sedimentary basin in the immediate vicinity of a large earthquake. Since many large cities in the world (e.g., Los Angeles, San Francisco, and Tokyo) where many large structures have been recently constructed are located in this type of environment, a ...

Application of wavelet for seismic wave analysis in Kathmandu Valley after the 2015 Gorkha earthquake, Nepal

Geoenvironmental Disasters, 2020
In this paper, we estimate the seismogenic energy during the Nepal Earthquake (25 April 2015) and studied the ground motion time-frequency characteristics in Kathmandu valley. The idea to analyze time-frequency characteristic of seismogenic energy signal

Estimation of broadband ground motion characteristics considering source parameter uncertainty and undetermined site condition in densely populated areas of Pingwu

Frontiers in Earth Science, 2023
Three destructive earthquakes occurred in Pingwu and Songpan, Sichuan Province, China, between August 16 and 23, 1976. Due to the seismic monitoring capability at that time, the ground motion characteristics of these earthquakes are very vague.
