Seismic Hazard Assessment and Site Response Evaluation in Hong Kong

This paper presents the results of a study to assess the seismic hazard and evaluate site response in Hong Kong. The hazard has been determined in terms of uniform hazard response spectra for probabilities of being exceeded of 50%, 10% and 2% in 50 years. The ground conditions in Hong Kong have been categorised using the IBC2006 site classification system. One-dimensional site response analyses have been used to determine how the various types of ground profiles are likely to amplify the expected levels of earthquake ground motion. The results are presented in terms of spectral ratios and uniform hazard response spectra for the different site classes and are compared with the IBC2006 and the China code of practice for buildings.
