Ground Motion Distribution Analysis about Taipei-101 in Earthquake

Abstract

It is important for tall building to infer seismic hazard analysis. Recently, researchers paid great efforts to study the seismic hazard analysis using the method of probabilistic seismic hazard analysis (PSHA), and PSHA has been proved to be sound and popular. The PSHA method is not new. However, the use of PSHA in China is not extensive. The purpose of this paper is to explore the use of ground motion distribution analysis about one typical tall building Taipei-101. Based on the earthquake catalog around Taiwan with more than 50,000 events over 100-years of recording, the author takes Taipei-101’s geographic coordination as object to do ground motion distribution analysis. The research shows that ground motion is affected significantly by service year, and the chi-square test applied in testing Annual ground motion distribution better than K-S test, In addition, Bernoulli distribution is verified reasonable in evaluating the entire service year ground motion distribution.
