Abstract | Conventional Probabilistic Seismic Hazard Assessment (PSHA) is difficult to apply in regions lacking sufficient information of the geological setting, active faults, and so forth. Also, for a site-specific PSHA, site effects arising from both crustal rock and overlying soil sediments are generally not assessed rigorously. This is of particular importance for those metropolitan cities having a significant proportion of reclaimed land, because the site-to-site variability of such site effects can be very large. The objective of this paper is to demonstrate an alternative procedure for constructing site-specific uniform hazard spectra (UHS), extended from a recently-developed Direct Amplitude-Based (DAB) approach. The method has a number of important advantages compared with conventional PSHA. Using the proposed approach, response spectral values have been computed for the whole period range of engineering interest, to form a set of site-specific UHS. |
