Abstract

The Karhunen-LoÚve (K-L) method is used to interpret dynamic response data obtained from shaking table and pseudodynamic tests conducted on civil engineering structures subjected to earthquake loading. It is shown how the K-L method can be used to monitor on-line, or a posteriori, the structural response of non-linear dynamic systems. Results from these analyses make it possible to quantitatively verify the number and participation factors of non-linear modes and how they correspond to physical behaviour of the structure. Comments are made regarding the use of this technique in various fields including numerical calculation, experiments and control.
