Spectra and peak ground accelerations for the assessment and rebuilding of structures in Christchurch were revised rapidly following the magnitude 6.2 earthquake on 22 February 2011. The NZS1170.5:2004 hazard factor Z for Christchurch was quickly raised from ...

After the two recent earthquakes in Christchurch (September 2010 and February 2011) a team of researchers organized by the Earthquake Engineering Research Institute (EERI) was dispatched to the area to conduct a damage survey. The survey addressed a variety ...

<p>Knowledge of seismic properties in an earthquake rupture zone is essential for understanding the factors controlling rupture dynamics. We use data from aftershocks following the Maule earthquake to derive a three-dimensional seismic velocity model of the ...

A Roman mausoleum located in the ancient city of Pınara, southwest Turkey, shows clear signs of damages due to dynamic loading. Considering the seismotectonic potential of the area, earthquake ground motions are a possible cause of the damages. However, the ...

<p>The present paper deals with the influence of soil non-linearity, on the soil-foundation-structure interaction phenomena. Numerical simulations are carried out so as to reveal the beneficial or unfavourable effects of the non-linear SSI on the assessing ...

<p>Laboratory tests are often used to understand dynamic soil behavior and to develop cyclic soil constitutive models. However, the loading paths in lab tests are different from those in the field, resulting in the inaccurate prediction of site response. An ...

In the field of earthquake engineering, ground-motion prediction models are frequently used to estimate the peak ground acceleration (PGA) and the pseudospectral acceleration (PSA). In regions of the world where ground-motion recordings are plentiful, such ...

<p>The performance of buried pipes is affected by seismic wave propagation and its incidence due to out-of phase induction motion. In this study, three dimensional finite element models have been employed to evaluate the effect of bend angle and soil mechanical ...

Hydropower plants with underground powerhouse contain different types of underground structures namely: diversion tunnels, headrace and tailrace tunnels, access tunnels, caverns grouting and inspection galleries etc. As earthquake ground shaking affects all ...

<p>Near-fault ground motions often possess distinct characteristics, which can have strong influence on structural response. These include the rupture directivity effect in the fault-normal direction and the fling step in the fault-parallel direction. A site ...
