The System Characteristics and Performance of a Shaking Table
MetadataShow full item record
The system characteristics of the earthquake ground motion simulation facility at the State University of New York at Buffalo is described in this paper. The dynamic performance of the shaking table is assessed by comparing the results introduced by two separate input program signals, acceleration and displacement, of a known earthquake record. An off-line iterative compensation technique is used to improve the precision of the simulation of the desired signals. In addition, a modified frequency domain data processing procedure for an accelerogram is presented.
