Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

The North East Italy (NI) broadband seismic network run by OGS: experience in improving the long period performances

, 2009
The NI broadband seismic network is designed to monitor regional seismic activity of North East Italy and surroundings as well as to provide high quality data for various research projects in regional and global broadband seismology, like moment tensor

Analysis of the dynamic behaviour of the hangingwall beam during a seismic event [PDF]

, 1992
Bibliography: leaves 68-72.In a deep-level gold mine planes of weakness oriented parallel to the reef allow the hangingwall to separate from adjacent rock strata. The hangingwall then acts as a separate beam supporting only its selfweight. Mining-induced

The use of FRPs in seismic repair and retrofit: experimental verification [PDF]

, 2001
The application of FRPs in the seismic repair and retrofit of structures is addressed. The results from a few tests on full-scale structures, repaired and/or retrofitted with composites, performed at the ELSA laboratory are presented and ...

地震作用下层状饱和场地-建筑群动力相互作用研究

Dizhen xuebao
采用间接边界元法，结合Biot饱和多孔介质理论，建立了层状饱和场地中二维建筑群模型，其中上部结构采用多质点模拟，基础采用刚性方形基础模拟，进而研究了场地-建筑群动力相互作用对结构动力响应的影响。数值分析表明，场地-建筑群效应可能显著改变结构动力响应，即使结构参数相同，建筑群中不同位置结构的动力响应也可能存在显著差异。相较于仅考虑场地-单体结构动力相互作用的结果，场地-建筑群效应可能减小或增大结构位移响应峰值，这与结构之间距离、结构动力特性、场地特性等因素相关。本文算例中场地 ...

Effects of Soil–Structure Interaction on the Seismic Response of RC Frame–Shear Wall Building Structures Under Far-Field Long-Period Ground Motions

Buildings
This paper focuses on the effect of soil–structure interaction (SSI) on the seismic response of high-rise RC frame–shear wall structures under far-field long-period ground motions. Elastic–plastic time–history analyses were performed using ABAQUS.

Advance in seismic site response: Usual practices and innovative methods

, 2017
Amplitudes and frequency content of the seismic ground motion generated by an earthquake and recorded at a specific location depends on the characteristics of the source, the path from the source to the site and the local geologic conditions.

High-resolution 3D seismic investigations of hydrate-bearing fluid escape chimneys in the Nyegga region of the Voring Plateau, Norway

, 2008
Hundreds of pockmarks and mounds, which seismic reflection sections show to be underlain by chimney-like structures, exist in southeast part of the Vøring plateau, Norwegian continental margin.

Seismic scattering signatures of small-scale heterogeneities: examples from the Mount Messenger Formation, New Zealand [PDF]

Heterogeneity that is on a length scale just below that of a seismic wavelength is at the limit of resolution but may still cause significant wave scattering.

2D nonlinear seismic response characteristics of a strait site with deep inhomogeneous soil deposits

Yantu gongcheng xuebao
The strait seabed is usually a deep sediment basin with various types of micro-topographies, and its seismic responses are strongly affected by the micro-topographies. A nonlinear seismic response analysis of 2D refined finite element simulated model for
