Use of combined scaling of real seismic records to obtain code-compliant sets of accelerograms: application for the city of Bucharest [PDF]
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 ...

An energy-based envelope function for the stochastic simulation of earthquake accelerograms [PDF]
An energy-based envelope function is developed for use in the stochastic simulation of earthquake ground motion. The envelope function is directly related to the Arias intensity of the ground motion as well to the manner in which this Arias intensity is ...

Simulation of spectrum-correspondent accelerogram by using artificial neural networks
Regarding the scarcity of appropriate recorded earthquakes, and the ever-increasing use of dynamic time history analyses for more accurate calculation of structures response, the simulation of artificially produced records necessary.

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 ...

Review on Baseline Correction of Strong-Motion Accelerogram
Because of various reasons, the baseline drift in the strong motion accelerogram was often founded, especially in the near-fault accelerogram. The baseline drift could lead to the unreliable velocity and displacement obtained by the accelerogram ...

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,

Derivation of Eurocode 8 spectrum-compatible time-histories from recorded seismic accelerograms via harmonic wavelets [PDF]
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).

On soil-structure interaction in large non-slender partially buried structures [PDF]
This paper addresses the seismic analysis of a deeply embedded non-slender structure hosting the pumping unit of a reservoir. The dynamic response in this type of problems is usually studied under the assumption of a perfectly rigid structure using a sub-

Treatment of earthquake accelerograms
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.

Semi‐Active Movable Shear Keys for Seismic Response Control of Bridges
ABSTRACT The size of the joint gaps plays a significant role in the dynamic performance of bridges. This has recently motivated the consideration of movable shear keys (MSKs), pioneered by the corresponding author, to enhance bridge performance by changing the bridge support/boundary conditions.
