WebFeb 15, 2012 · The site ground motions are estimated deterministically, given the magnitude, source-to-site distance, and site condition. Deterministic Seismic Hazard Analysis • Consists of four primary steps: • 1. Identification and characterization of all sources • 2. Selection of source-site distance parameter • 3. Selection of “controlling ... WebMay 15, 2024 · While probabilistic methods are mainly used to characterise seismic hazards, there is the potential to further reduce uncertainty in the case that a known fault is activated (i.e., deterministic hazard). In such a case, we can isolate seismicity related only to this particular fault (e.g., using cross-correlation) in order to obtain associated ... green and gold backsplash tile
Different steps for deterministic seismic hazard analysis …
WebTo keep things simple, PGA will be used as the ground-motion parameter here (the analysis is otherwise equivalent). PSHA involves three steps: 1) specification of the seismic-hazard source model(s); 2) specification of the ground motion model(s) (attenuation relationship(s)); and 3) the probabilistic calculation. Webseismic hazard analysis, as described by Cornell (1968), Der Kiureghian andAng (1977), is well established in engineering practice. In general, the following steps are required: (1) Seismic source zones surrounding the site are identified. (2) The seismicity of each source zone is estimated on the basis of historical and instrumental WebJul 1, 2001 · We can examine a deterministic event from the Phase 2 seismic hazard analysis by looking at the largest magnitude, at the closest distance, with the largest amplification resulting from directivity effects.
