This paper is concerned with the study of the effect of combined horizontal and vertical accelerations on the seismic response of reinforced concrete structures. To achieve this objective, three reinforced concrete buildings representative of rigid, semi-rigid ...

<p>Reinforced soil walls have become very popular in seismic areas owing to their flexible nature and cost effectiveness when compared to the conventional retaining structures. Although the use of reinforced soil walls with modular block facings and gabion ...

<p>Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented ...

The design for a major cable-stayed bridge to be constructed in seismically-active Charleston, South Carolina, included rock islands around the main span piers as protection from shipimpact. Considering the seismic potential, a primary concern was the potential ...

The original subgrade conditions generally consisted of loose, liquefiable sands, expected to significantly lose strength during the design earthquake and soft, compressible clays. To mitigate the risk of liquefaction-induced instability and to mitigate the ...

<p>This paper presents a survey of seven unique case-history sites, along with a review of the techniques used in analyses of downhole seismic records. These techniques include correlation and spectral analyses, stress-strain imaging, and system identification ...

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. ...

<p>Through a series of twelve separate geotechnical centrifuge modeling tests, <br />seismic behavior of a zoned earth dam with saturated sandy soil foundation was studied under moderate earthquake conditions. Soil response during and after shaking was monitored ...
