<p>Engineering ground-motion parameters can be used to describe the damage potential of an earthquake. Some of them correlate well with several commonly used demand measures of structural performance, liquefaction, and seismic-slope stability. The importance ...

Using a random effects model that takes into consideration the correlation of data recorded by a single seismic event, a database consisting of 195 recordings from 17 recent events is employed to develop empirical attenuation relationships for the geometric ...

This paper, jointly prepared by dam engineers from Japan and the United States, discusses the role of nonlinear dynamic analyses in seismic evaluation problems in these two countries.

<p>A simple and powerful method for simulating ground motions is to combine parametric or functional descriptions of the ground motion&rsquo;s amplitude spectrum with a random phase spectrum modified such that the motion is distributed over a duration related ...

This study aims at clarifying the characteristics of the effects of vertical ground motions upon earthquake responses of steel frames. The inelastic response of a multi-story frame is characterized mainly by the restoring force of the frame's lower parts. ...

This report sought to answer the question: does the vertical component of ground motion constitute a significant proportion of the loading that has to be resisted by a building and by its foundations. It concentrates on ground motion in the near-field where ...

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, ...

Characteristics of vertical and horizontal component strong ground motions have been examined to reveal general trends which may be of significance to structural analyses. Recordings at both rock and deep soil sites representative of WUS showed distinctly ...

<p>Widespread and large-scale ground failures due to liquefaction occurred along the river valley of the Shiribeshi-toshibetsu River during the 1993 Hokkaido-nansei-oki Earthquake. By using the aerial photographs taken one day after the earthquake along the ...

Engineering Demand Parameters, such as inter-storey drift or floor accelerations, can be correlated to damage within the structure. While current code provisions exist to estimate Engineering Demand Parameters to use in design of components within the structure, ...
