Chi-Chi Earthquake is the second largest earthquake that hit Taiwan on 1999. The damages include the death, and the bridges and buildings failure. Many ground motions data that were recorded in several locations shows that Chi-Chi earthquake on 1999 is one of the near fault ground motion that have special characteristics. Design spectra concept is the ground motion analysis to normalize the ground motion from the original locations, considering the soil and site condition in another location to calculate the scaling factor. So that the ground motions input that applied to the building have been adapted with the existing site condition. The number of three ground motions of Chi-Chi Earthquakes proposed from three different stations. TCU068, TCU102, and TCU05. Due to Chi-Chi earthquakes is one of strong motion input with the special characteristic. Many engineers in around the world consider Chi-Chi Earthquakes as the input of earthquake analysis of the construction modeling. Different location site will be different in their site condition, thus the design spectra analysis need to consider since this method provide the scaling factor that represent the new site construction.
