Near-fault seismic risk assessment of simply supported bridges

, 2020
Bridges tend to sustain excessive seismic demand (e.g. displacement) under pulse-like ground motions attributing to the effect of forward directivity, which is of high likely to occur at locations near the fault rupture.

Seismic response analysis of intake tower structure under near-fault ground motions with forward-directivity and fling-step effects

, 2020
Forward-directivity and fling-step effects of fault rupture generally cause large amplitude and long-period velocity pulses in near-fault ground motions, which impose severe damages on structures.

The pulse effect on the isolation device optimization of simply supported bridges in near-fault regions

, 2020
Seismic isolation devices serve as an important measure to reduce hazards or mitigate structure damage subject to earthquakes. It’s of great necessity to select the optimal parameters of isolation devices to achieve a good performance especially for ...

Elastic and Inelastic Near-Fault Input Energy Spectra

Earthquake Spectra, 2018
The main purpose of this study is to develop a reliable model for predicting the input energy spectra of near-fault ground motions for linear elastic and inelastic systems, and to evaluate the effect of damping and lateral strength on energy dissipation demands.

Maximum Spectral Demands in the Near-Fault Region

Earthquake Spectra, 2008
The Next Generation Attenuation (NGA) relationships for shallow crustal earthquakes in the western United States predict a rotated geometric mean of horizontal spectral demand, termed GMRotI50, and not maximum spectral demand. Differences between strike-normal, strike-parallel, geometric-mean, and maximum spectral demands in the near-fault region are ...

Influence of Near-fault Pulse-like Motion Characteristics on Seismic Performance of Tall Pier Bridges with Fragility Analysis

Journal of earthquake engineering, 2020
This paper focuses on the effects of near-fault motion characteristics on the seismic performance of tall pier bridges. Using the analytical models calibrated by shake table tests, fragility analysis was conducted investigating the influence of near ...

Residual displacement responses of structures subjected to near-fault pulse-like ground motions

Structure and Infrastructure Engineering, 2020
The residual deformation is one crucial factor determining the structural safety and the structural repair cost after earthquakes. Hence, the quantitative estimation of residual displacements is necessary for modern performance-based design and ...

Effect of Near-fault Terrain upon Dislocation Modeling

pure and applied geophysics, 1997
—Coseismic surface deformation provides important information needed to determine source rupture geometry and slip distribution as well as to estimate seismic moment. In this study, numerical experiments were designed to analyze and classify how free-surface topography affects surface deformation.
