Analysis ana Correction of Experimental Errors in Pseudodynamic Test

유사동적실험 오차의 분석 및 보정

The Pseudodynamic test is a new experimental technique for simulating the earthquake response of structures or structural components in the time domain. It is especially efficient for testing structures that are too large, heavy or strong to be tested on a shaking table. But the obtained responses in the Pseudodynamic test are distorted by the experimental errors inevitably during control and measurement procedures. The studies are to investigate the effects of the experimental errors on the Pseudodynamic responses and apply a correction method to the Pseudodynamic testing algorithm. It is shown that the corrected responses using the Equivalent Energy Compensation Method are in a good correlation with the theoretical ones. Thus, the corrected Pseudodynamic responses could be reliable for evaluating the seismic performance of structural systems.
