| Summary: | Single Station Time Domain (SSTD) technique is one of the efficient methods
used to extract modal parameters. This technique relies on free decay responses
to obtain the required parameters. In this paper, a study on time shift interval
on SSTD algorithm method is investigated. It is found that altering specific
time interval settings could improve the accuracy of natural frequencies and
damping ratios determination of a structure. Accuracy assessment of the method
is made using simulated analytical data with known properties where percentage
error between the results of simulated and this method can be calculated and
compared. |
