Earthquake Spatial Coherence Analysis from Simulated Accelerograms

Earth and Space 2010, 2010
In considering of site conditions and source parameters, the accelerograms on bedrock at some specified sites are simulated first by stochastic finite fault method, and then the ground motion coherences among these accelerograms are studied further both in horizontal and vertical directions.

Structural Response to Truncated Earthquake Accelerograms

Journal of Structural Engineering, 1988
The discontinuity in the ground motion arising from the truncation of earthquake accelerograms may produce inaccuracies in the response of long period structures with low damping. The termination of the ground motion at a point where the acceleration is low and the use of a small time step during free vibration following the truncation of the record ...

A Mechanical Method of Analyzing Accelerograms

Seismological Research Letters, 1936
In seismological research, particularly that branch relating to engineering studies and vibration‐work, one of the most important practical problems is that of computing the motion of a pendulum when the ground‐motion is known. When it is realized that the same formula is also used to estimate the response of engineering structures to earth‐movements ...

ASCONA: Automated Selection of COmpatible Natural Accelerograms

Earthquake Spectra, 2012
This paper describes an automated procedure for selecting and scaling real spectrum-compatible records. The methodology allows one to choose from a predefined database, assembled from accredited strong-motion accelerometric data banks, real records satisfying properly defined seismological constraints with the additional requirement of spectrum ...

Artificial Nonstationary Accelerograms with Natural Variability

2010
The present work describes a revisited version of the method for generating nonstationary accelerograms originally proposed by Sabetta and Pugliese (1996). This method adopts four ground motion parameters – Arias intensity, duration, central frequency and frequency bandwidth – to approximate the spectrograms of the accelerograms to be generated. In the

Scaling of Earthquake Accelerograms-A Simplified Approach

Journal of the Structural Division, 1972
With the more sophisticated computer programs now available for the dynamic analysis of structures, use of time-history excitation of such structures has become common practice. Besides affording a more rigorous analysis of the structure itself, a time-history excitation simplifies the calculation of the response of equipment located at the higher ...
