Torsion in symmetric buildings due to soil‐structure interaction: A discussion on code values of accidental eccentricity factor in seismic design

J Fu, S Chen - Earthquake Engineering & Structural Dynamics, 2022 - Wiley Online Library
Soil‐structure interaction (SSI) is often neglected in seismic design because of its inherent
complexity. Therefore, SSI‐related research is crucial for ensuring that more significant …

Dynamic Structure-Soil-Structure Interaction in unsymmetrical plan buildings due to seismic excitation

F Vicencio, NA Alexander - Soil Dynamics and Earthquake Engineering, 2019 - Elsevier
This paper explores the influence of Structure-Soil-Structure Interaction (SSSI) between a
pair of buildings, one of which is unsymmetrical in plan and hence subject to seismically …

Effects of soil–structure interaction on inelastic response of torsionally-coupled structures

M Shirzadi, F Behnamfar, P Asadi - Bulletin of Earthquake Engineering, 2020 - Springer
In this paper, effect of torsion on the inelastic responses of structures resting on a nonlinear
flexible medium is studied. Similar studies have shown that soil–structure interaction can …

Evaluation of dynamic eccentricity by considering soil–structure interaction: a proposal for seismic design codes

H Shakib - Soil Dynamics and Earthquake Engineering, 2004 - Elsevier
A stochastic approach is adopted for the linear analysis of three-dimensional dynamic soil–
structure interaction of asymmetric buildings in the time domain to evaluate the dynamic …

Seismic Structure-Soil-Structure Interaction between a pair of buildings with consideration of rotational ground motions effects

F Vicencio, NA Alexander - Soil Dynamics and Earthquake Engineering, 2022 - Elsevier
During an earthquake, buildings are analysed dynamically without any consideration of their
neighbouring structures and usually this also neglects the influence of surficial rotational …

Accidental eccentricity in multistory buildings due to torsional ground motion

D Basu, S Giri - Bulletin of Earthquake Engineering, 2015 - Springer
Accidental eccentricity is aimed to account for any unforeseen factor that may attribute to the
torsional response. These sources can be broadly classified into two components, namely …

A study on the effects of torsional component of ground motions on seismic response of low‐and mid‐rise buildings

The torsional component of ground motion is a potential factor to excite the torsional
response of buildings during earthquake, which is not explicitly considered in seismic …

Suitability of using the torsional amplification factor to amplify accidental torsion

JL Lin, WC Wang, KC Tsai - Engineering Structures, 2016 - Elsevier
The accidental torsion effect on the seismic responses of a building is considered by adding
the accidental eccentricity to the existing eccentricity. While buildings are torsionally …
