Proposed enhanced spectra for near‐fault regions using forward directivity records

open access: yesInternational Journal of Disaster Resilience in the Built Environment, 2010
PurposeThe purpose of this paper is to develop a proper tool for structural analysis and designing in near‐fault regions where the level of earthquake hazard is more and its nature is different from far‐field regions.Design/methodology/approachThe paper uses near‐fault records and pulse extraction using wavelet analysis and designs a spectra concept ...

Sensitivity of structural responses to the processing of near-fault ground motion records containing fling-step

Advances in Structural Engineering, 2023
Fling-step is one of the important characteristics of near-fault ground motions that is caused by a permanent static offset of the ground and appears as a one-sided velocity pulse and a large residual displacement at the end of the motion. Due to baseline errors in many ground motion records, they are processed (processing is a combination of baseline ...

Aseismic design implications of near-fault san fernando earthquake records

Earthquake Engineering and Structural Dynamics, 1978
AbstractNear‐fault records of the 1971 San Fernando earthquake contain severe, long duration acceleration pulses which result in unusually large ground velocity increments. A review of these records along with the results of available theoretical studies of near‐fault ground motions indicates that such acceleration pulses may be characteristic of near ...

Effects of near-fault records characteristics on seismic performance of eccentrically braced frames

Structural Engineering and Mechanics, 2015
In this paper the effects of fling-step and forward-directivity on the seismic performance of steel eccentrically braced frames (EBFs) are addressed. Four EBFs with various numbers of stories (4-, 8-,12- and 15-story) were designed for an area with high seismic hazard.
