Abstract

The objective of this research is to verify a newly developed method, time delay (TD) method, for earthquake analysis using data from strong motion instrumentation program (SMIP), and then applying the TD method to calculate overturning moment of structures. The TD method incorporates the attribute of finite wave speed propagating upward into the structure.

One detailed 3-dimensional mode1 and nine simplified 2-dimensional models were used for study. The effects on the overturning moment due to the use of TD method varies depending upon the predominant period of the input earthquake motions and the structures. The concept of the TD method is verified with the measured data.
