The tensile displacement can be seismoactive only under special contact conditions on the fault plane. The existence of tensile cracks at the fault tips changed the pattern of seismic energy radiation. This feature is probably caused by subsequent changes in contact conditions on the fault plane ...
As there is always a challenge to simulate corresponding attributes due to the lack of proper seismic and petro-elastic model, other attributes like displacement front, binary images are being introduced. 3. Forward modeling 3.1. Petro-elastic models (PEM) Application of seismic forward modeling in...
Considering that near-fault ground motions have distinct characteristics, which can impose excessive displacement in FPS compared to far-field ones [20], [49], the main objective of this paper is to develop the seismic fragility curves of base-isolated liquid storage tanks under near-fault ground...
Finally, the L-curve method was used in the slip distribution inversion of this fault. After that, a double-fault model of the Lushan earthquake was established using the simulated annealing method and cross-test based on near-field displacement data. Tan et al. [ 5 ] constructed the Lushan...
摘要: The largest landslide induced by the Wenchuan earthquake was studied.Effect of near-fault seismic loadings on landslide run-out was studied by DDA.Baseline corrected real ground motion records with co-seismic displacement were used.Size effect of the huge landslide was considered....
A nonlinear force-displacement law of the FP bearings is considered in the horizontal direction, depending on sliding velocity and axial load, while a gap model takes into account the vertical uplift of the FP bearings. The nonlinear seismic analysis is performed on near-fault ground motions with...

Some studies have shown that a conventional seismic isolation system may suffer from an excessive isolator displacement when subjected to a near-fault earthquake that usually has a long-period velocity pulse waveform. In order to alleviate this problem, a semi-active isolation system (SAIS) with a...
