چکیده

In this paper, we present a hybrid approach to motion data manipulation. Motion signal is decomposed into multi-resolution levels with wavelet analysis. The coarse level represents the globe pattern of a motion signal while the fine levels describe the individual styles. Special motion style can be highlighted through enhancing the corresponding level content and can be fused into other motions by texturing them with related fine levels. And multiple motions can be synthesized by multi-resolution blending to create new motions somehow like to the blended motions. Motion signals implicitly preserve constraints to keep realistic. However, the above manipulations may inviolate some constraints and result in the unrealistic artifact. Spacetime rectification is proposed to reserve the essential constraints. Our experiment shows the effectiveness of this hybrid motion data manipulation approach.

GROUND MOTION CLUSTERING BY A HYBRID K-MEANS AND COLLIDING BODIES OPTIMIZATION

Stochastic nature of earthquake has raised a challenge for engineers to choose which record for their analyses. Clustering is offered as a solution for such a data mining problem to automatically distinguish between ground motion records based on similarities in the corresponding seismic attributes. The present work formulates an optimization problem to seek for the best clustering measures. In...

Effect of the frequency content of earthquake excitation on damage detection in steel frames

In this study, the effect of earthquake frequency content and noise effects on damage detection has been investigated. For this purpose, the damage was defined as nonlinear behavior of beams and columns, and several ground motion records were scaled so that some elements yield under the applied excitation. Then the acceleration response data of each floor obtained using the nonlinear dynamic an...
