000009735 520__ $$2eng$$aTaipei Basin located in northern Taiwan has been experienced several damaging earthquakes in the past decades, the recent of which occurred on September 21, 1999 and March 31, 2002. Although the Taipei Basin is located more than 130 km away from the epicenter of these two earthquakes, the damage level in the area was greater than others in the northern region. According to the Taiwan seismic design code, Taipei Basin is classified as a special site and particular design spectra are prepared for the basin., Due to the geotechnical properties at the site and the source parameters of earthquake, the recorded earthquake ground motions show large variation within the basin. According to the analysis of strong ground motion data recorded by the CWB, we found that if the magnitude is larger than 6.5 and PGA > 30 gal, the basin effect will be excited significantly and the associated spectral response accelerations at medium to long periods in some area inside Taipei Basin will attenuate slowly. In this paper, the site-specific shapes of response spectrum were determined on the basis of some representative earthquake events, and then compared with the shape of design spectrum. By adjusting zone map, a new seismic micro-zone map for the area of Taipei Basin can be developed.
