Not only the ground failure but also the change of natural frequency of the site is induced by the liquefied layer, while from the vibration point of view the structure s [...]

The response and damage of the underground structure under the seismic action are usually controlled by the deformation of soils and the seismic design of the underground [...]

The shear modulus is the most basic parameter and can be attained by the experiments in the field or in the laboratory. The maximum dynamic shear modulus obtained in the [...]

The methods for detection of soil liquefaction from seismic records are being developed recently. The developed detection methods make it possible to capture the alterati [...]

At present, the seismic design of structures is mainly based on the response spectra. The seismic responses for the deep foundations, the underground structures and struc [...]

Liquefaction is one of the important reasons in earthquake damages. The response and damage for the foundations and underground structures are dominated by soil deformati [...]

The asymmetrical characteristics of PGA and its effect on the soil dynamic property are investigated. The effect of asymmetrical characteristics of seismic loads on the s [...]

Many researches in recent years have approved that the nonlinear behavior of soils has significant effect on the surface ground motion. The laboratory experiments on the [...]

The dynamic shear modulus and damping ratio of soils are two important parameters in soil property and affect earthquake ground motion greatly. The laboratory experimenta [...]

At 14:28 May 12 2008, a catastrophic earthquake of magnitude 8.0, the epicenter of which locates at Wenchuan, struck Sichuan Province (N31.00, E103.40). The earthquake ca [...]
