Vertical distribution of seismic design load for seismically isolated buildings corresponding to diversity of seismic isolation devices

JAPAN ARCHITECTURAL REVIEW, 2012
AbstractThis paper proposes a vertical distribution of seismic design load of seismically isolated buildings corresponding to diversity of seismic isolation devices such as hysteretic dampers and/or velocity‐dependent dampers. This proposed method is obtained from the relationship between response amplification caused by higher‐mode responses and key ...

Seismic Response Analysis of an Isolated Structure with QZS under Near-Fault Vertical Earthquakes

Shock and Vibration, 2018
Seismic isolation devices are usually designed to protect structures from the strong horizontal component of earthquake ground shaking. However, the effect of near-fault (NF) vertical ground motions on seismic responses of buildings has become an ...

A Study on the Design of a New Three-Dimensional Seismic Isolation Bearing Based on an Improved Genetic Algorithm for Bridge Engineering

Applied Sciences
(1) Background: In most cases, passive isolation control methods are commonly used for the seismic isolation design in bridge engineering. However, passive seismic isolation devices, due to their non-adjustable performance parameters, struggle to achieve

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...
