Sentence examples for elastic spectra from inspiring English sources

However, for small return periods, where the structure experiences slight plastic deformations, elastic spectra provide an effective intensity measure.

Such rigorous spectra were then compared with the approximated curves calculated using the N2 method and the Equivalent Linearization Procedure (ELP) based on the use of overdamped elastic spectra.

In this paper, the nonlinear rigid-perfectly plastic (RPP) spectra, instead of linear elastic spectra, are used to correlate the seismic hazard return period and the time in the ET analysis.

In spite of this simplified modelling approach, the proposed model captures the key features of hysteretic cycles of x-braced frames (extreme pinching and slackness) and can be used to obtain the q-factor for simplified seismic design based on the reduction of elastic spectra.

Spectra from selected accelerograms of near-source records are compared with the corresponding elastic spectra of the current Greek Seismic Code, (EAK 2000), the impulsive character of the Greek near-source records is ascertained and shortcomings of EAK 2000 to account for near-source effects are demonstrated.

Open image in new window Fig. 10 Elastic spectra of pseudo-accelerations and displacements.

The seismic input is provided using the Eurocode 8 elastic spectrum and five compatible acceleration histories.

The unreduced elastic response spectra given in four codes are quite different in recognition of different ground types and seismicity, in particular, Japanese code generally specifies much larger elastic spectrum than other codes.

A procedure that defines behaviour factors to reduce the elastic spectrum for different types of structures, considering all possible types of failure, is needed.

The ordinates of the elastic spectrum and the spectral shape of each individual record are found to significantly influence the seismic performance and they are shown to provide promising candidates for highly efficient IMs.

Lower and the upper periods of the elastic spectrum.
