WebProbabilistic seismic soil-structure interaction (SSI) analysis is theoretically the most thorough analysis to include the effects of inherent uncertainties related to the seismic input motion and soil and structural material behavior. The paper WebThe steps involved in both deterministic seismic hazard analysis (DSHA) and probabilistic seismic hazard analyses (PSHA) are outlined in Chapters 4 and 5 , respectively. A detailed example is presented at the end of each chapter which illustrates the respective approaches; the same site is used in
WebDec 1, 2014 · 1. Introduction. Since it is challenging to predict an earthquake’s magnitude, location and time, seismic hazard analysis is considered a more practical engineering solution for earthquake hazard mitigation [1].But before introducing the analysis, it is worth clarifying the definition of seismic hazard in the first place: Rather than casualty or …
