Seismicity, seismic input and site effects in the Sahel—Algiers region (North Algeria)

Soil Dynamics and Earthquake Engineering, 2007
Algiers city is located in a seismogenic zone. To reduce the impact of seismic risk in this Capital city, a realistic modelling of the seismic ground motion (SGM) is conducted by using the hybrid method that combines the finite differences method and the modal summation.

Seismic Hazard Mapping of California considering Site Effects

Earthquake Spectra, 2010
In this paper, we have combined the U.S. Geological Survey's National Seismic Hazard Maps model with the California geologic map showing 17 generalized geologic units that can be defined by their VS30. We regrouped these units into seven VS30 values and calculated a probabilistic seismic hazard map for the entire state for each VS30 value.

Local Site Effects for Seismic Zonation

2018
This chapter predominantly discuss about the role of Local site conditions on the amplification of seismic waves and the resulted earthquake disasters. In-depth discussions are made on the various local site conditions which influence the ground shaking.

Effects of ground treatment on site seismic response

2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011
The effect of foundation treatment on ground motion is studied using finite element method. The difference between natural field and stabilized field is compared; the impacts of the stabilization zone width, depth, soil modulus stabilization, soil modulus and the seismic wave characteristics on response of the ground motion are also investigated.

Effect of site amplification on inelastic seismic response

Earthquake Engineering and Engineering Vibration, 2019
The available models for effective periods of site and structure are reviewed in context of frequency tuning in the inelastic seismic response of soil-structure system. The effect of seismic intensity and ductility demand, on the effective periods, is investigated, and inelastic site amplification is shown to be strongly correlated to the normalized ...

Effective stress analysis of seismic site response

International Journal for Numerical and Analytical Methods in Geomechanics, 1986
AbstractA procedure is presented which allows site response analyses to be performed with any general multidimensional finite element analysis package. Numerical results which corrorate the theory are presented. Also, as an illustration of the procedure, results of an effective stress analysis for the scismic response and liquefaction of a horizontally

Seismic Site Effects on the French Riviera

1998
The analysis of site effects through numerical approaches is interesting since it gives quantitative results on both following parameters : the amplification level and the location of its highest values. It is then possible to compare or improve (with) the experimental investigations concerning this phenomenon.

Study on Engineering Site Seismic Effect in Shijiazhuang

Advanced Materials Research, 2013
Along with the rapid development of city, the research on seismic effect of the sites is gradually recognized. In this paper earthquake effects of several engineering sites selected from Shijiazhuang are studied, using the one-dimensional linear program and considering different seismic wave and peak acceleration.

Seismic Microzonation of Site Effects

1999
We have been developing in France a specific methodology which takes community vulnerability into account. Those microzonings are normally presented as a map at scale 1: 5,000 or 1: 10,000 of the particular effects that are due to site effects, which concern the modification of the seismic signal; taking them into account leads us to the identification
