Effects of response spectrum of pulse-like ground motion on stochastic seismic response of tunnel [PDF]

Engineering Structures, 2023
It is widely accepted that near-fault pulse-like ground motions potentially cause more severe damage to structures than ordinary ground motions. However, the effects of stochastic pulse-like ground motions on underground structures are not effectively ...

Modeling and Seismic Response Analysis of a Reclaimed Artificial Ground

Soil Dynamics and Earthquake Engineering, 2010
Compared with natural grounds formed by sedimentation over many years, reclaimed artificial grounds are often weak. In this work, modeling of a reclaimed offshore artificial ground and its seismic response analysis were carried out, and the vulnerability of the weak reclaimed layers to seismic activity is pointed out. This study was carried out using a

Seismic response analysis of laterally inhomogeneous ground with emphasis on strains

Soil Dynamics and Earthquake Engineering, 2002
The objective of this paper is to make it clear how strain behaviors are affected by the lateral inhomogeneity of ground based on both theoretical simulation and array observation of earthquake motions. We use a two-dimensional pseudo-spectral method to numerically obtain strain motions as well as acceleration motions.

Seismic response analysis of above‐ground pipelines

Earthquake Engineering & Structural Dynamics, 1978
AbstractA procedure for computing the seismic response of above‐ground, cross‐country pipelines is described. The procedure accounts for the effects of initial static loads, slipping of the pipe on its supports and out‐of‐phase ground motions at different points along the pipe.

Seismic Ground Response Analysis for Soil Site in Johor, Malaysia

2020
Seismic ground response analysis (GRA) has been carried out for a soil site located in Johor, Malaysia, in order to know the degradation of soil layers overlying a bed rock subjected to a ground motion. In this paper, an effort has been made to critically study the results obtained by 1-D equivalent linear analysis and nonlinear analysis using DEEPSOIL

Distribution of ground rigidity and ground model for seismic response analysis in Hualian project of large scale seismic test

Nuclear Engineering and Design, 1997
Abstract An international joint research program called HLSST is proceeding. HLSST is large-scale seismic test (LSST) to investigate soil-structure interaction (SSI) during large earthquake in the field in Hualien, a high seismic region in Taiwan.

Seismic Ground Response Analysis of Some Typical Sites of Guwahati City

International Journal of Geotechnical Earthquake Engineering, 2013
In this study, one dimensional equivalent–linear ground response analyses were performed for some typical sites in the Guwahati city, India. Six bore locations covering about 250 km2 area of the city were considered for the analyses. As the strong motion significantly influences the ground response, seven different recorded ground motions, varying in ...

Stochastic analysis of seismic ground response for site classification methods verification

Soil Dynamics and Earthquake Engineering, 2018
Abstract A database of numerical ground response analyses has been generated to assess the effectiveness of site classification schemes adopted in seismic building codes. 1-D Ground models have been generated with a stochastic approach based on a Monte Carlo procedure and the corresponding seismic response has been evaluated by the equivalent linear ...

Introduction of Seismic Ground Response Analysis

2014
Computer programs for seismic response analysis have been developed mainly in the field of structural analysis. The analysis of ground might be possible by these computer programs. However, they are not used at present. Significant difference exists in the constitutive model or stress–strain relationships. As soil shows nonlinear behavior at very small

Analysis of Seismic Responses During Near-Source Ground Motions

Advanced Materials Research, 2012
Seismic responses can strongly determine damages of bridge structures, e.g. due to pounding and unseating of girders as observed in many major earthquakes in the past. In the investigations often uniform ground excitation and pounding at only one location are considered.
