地震危险性概率分析(PSHA)最初是从相类似的洪水、风暴问题的分析方法发展而来的,而且被完整的应用到风险分析中。后来,PSHA被直接引入到地震动非确定性分析。如此直接引入非确定性分析缺乏清楚的物理基础,使人在非确定性分析中很难理解、解释和运用PSHA。这一困难导致了诸如房 The Seismic Hazard Probability Analysis (PSHA) was originally developed from similar flood and storm analysis methods and is fully applied to risk analysis. Later, PSHA was introduced directly into non-deterministic analysis of ground motion. Such a direct introduction of non-deterministic analysis lacks a clear physical basis, making it difficult for people to understand, interpret and apply PSHA in non-deterministic analyzes. This difficulty has led to such as the room
