Fundamental study on seismic response of escalator (Seismic response analysis using SDOF escalator model)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
The escalator is one of most important vertical transportation measures to connect each every one of storey-layers in buildings. During severe earthquakes, escalators are not only shaken by themselves, but withstand lateral relative deflexions induced in

关于抗震防灾的若干思考

open access: yesDizhen xuebao, 2022
本文试图从哲学和科学的角度,就我国地震工程研究和防震减灾事业的若干问题进行讨论。论文指出:宏观考察得出的地震烈度并不具备科学概念应有的确切内涵和外延;地震危险性分析结果不可能被验证;抗震设防标准的采用从根本上取决于社会经济与技术的发展水平;断层避让研究尚未达到工程应用阶段;不能追求结构地震反应数值模拟的精确结果。最后,提出了对当前地震工程研究的建议和前景展望。

An Analytical Method for Elastic Seismic Response of Structures Considering the Effect of Ground Motion Duration

open access: yesApplied Sciences, 2021
The response to earthquake ground motion is composed of three basic elements, namely, amplitude, frequency, and duration. The seismic response of a structure is controlled by the particular combination of these three elements.

Seismic Response Analysis of Structure: A Perspective View [PDF]

open access: yesInternational Journal of Trend in Scientific Research and Development, 2019
From past earthquakes it is proved that many of structure are totally or partially damaged due to earthquake. So, it is necessary to determine seismic responses of such buildings. There are different techniques of seismic analysis of structure. Time history analysis is one of the important techniques for structural seismic analysis generally the ...

A MPM framework for large-deformation seismic response analysis [PDF]

open access: yesCanadian Geotechnical Journal, 2022
Landslides are often triggered by earthquakes and can cause immense damage due to large mass movements. To model such large-deformation events, the material point method (MPM) has become increasingly popular in recent years. A limitation of existing MPM implementations is the lack of appropriate boundary conditions to perform seismic response analysis
