Abstract

In November 2022, the Headquarters for Earthquake Research Promotion (HERP) released “Probabilistic Seismic Hazard Analysis of Response Spectra.” The Probabilistic Seismic Hazard Analysis (PSHA) is important for seismic performance-based design of buildings. However, sites for which the seismic hazard released are limited to only the Tokyo Metropolitan Government Office, the Osaka City Hall, and the Nagoya City Hall in the form of figures rather than functions. For this reason, results of the PSHA cannot be directly used for seismic performance-based design. Therefore, the PSHA of Response Spectra by HERP are quantified with approximating lognormal distribution in this paper.
