Damping Modification Factors for Pile–Induced Filtering Effect
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 907-925, 10 April 2026.ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...

Treatment of earthquake accelerograms
Bulletin of the New Zealand Society for Earthquake Engineering, 1970 Engineers involved in structural design in earthquake areas are interested in the forces exerted on a structure during strong earthquakes. To evaluate these forces it is necessary to have records of ground motion during such earthquakes. The most convenient motion to record as far as further processing is concerned is ground acceleration.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Spectral analysis of Al Haouz earthquake and comparison with the design spectrum [PDF]
E3S Web of ConferencesAl Haouz earthquake damage highlights the insufficiency of the current normative spectrum. Spectral amplitude comparison against the local records shows that the spectral amplitudes, in certain periods ranges, were greater than RPS 2011 predictions ...

Derivation of Eurocode 8 spectrum-compatible time-histories from recorded seismic accelerograms via harmonic wavelets [PDF]
, 2010 A computationally efficient harmonic wavelet-based iterative procedure is proposed to modify suites of recorded accelerograms to be used in the aseismic design of critical structures regulated by the European code provisions (EC8).

Annex: Master Configuration Files [PDF]
, 2008 A DLL (Dynamic Link Library) is a file of code containing functions that can be called from other executable code. The advantage of working with DLLs at ELSA PsD Master controller is in the modularity for programming the testing method and algorithm ...

Spectrum-compatible accelerograms with harmonic wavelets
Computers & Structures, 2015 AbstractModern building codes allow the analysis and design of earthquake-resistant structures with recorded and/or generated accelerograms, provided that they are compatible with the elastic design spectrum. The problem then arises to generate spectrum-compliant accelerograms with realistic non-stationary characteristics, which in turn may play an ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 759-780, March 2026.ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Use of combined scaling of real seismic records to obtain code-compliant sets of accelerograms: application for the city of Bucharest [PDF]
, 2012 A recently proposed method for scaling real accelerograms to obtain sets of code-compliant records is assessed. The method, which uses combined time and amplitude scaling, corroborated with an imposed value of an instrumental, Arias type intensity ...
