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 ...

The characterisation of strong ground motion is a crucial element of analyses of seismic risk for isolated structures and lifeline networks. Many measures of the strength of ground motion (intensity measures) have been developed. Each intensity measure may ...

In this paper an analytical methodology is presented to evaluate rock slope stability under seismic conditions by considering the geomechanical and topographic properties of a slope.

<p>This ongoing research will help answer the questions that continue to arise as Reclamation is faced with detailed analysis and modifications of spillways and other earth-retaining structures subjected to significant seismic loading. The objective of this ...

A magnitude 6.6 (Ms) earthquake struck the city of Bam in southeast Iran at 5:26:52 AM (local time) on Friday, December 26, 2003. The city’s population was about 90,000, with 200,000 total residents in the greater Bam area. The U.N. Office for the Coordination ...

The main use of seismic hazard analyses is to develop rock outcrop or stiff soil ground motions for use in design. the quantitative descriptions of the ground motions can be in terms of seimple scalar values (e.g. peak acceleration, peak velocity, peak displacement, ...
