Question

What areinput parameters in preliminary hazard analysis?

Answer 1

Explanation:

using the PHL and Preliminary Hazard Analysis (PHA) as inputs along with .... parameters established by the Operational Safety Assessment ( OSA

Answer 2

$\huge\underline\pink{\tt Answer}$

• Probabilistic seismic hazard analysis (PSHA) is a methodology by which one evaluates the probability of exceeding different parameters of the ground motions

• (the maximum ground acceleration - PGA and the ground response spectrum - SA) as effect of the seismic action, on a given site at a future time moment.

• Due to the large uncertainties in the geological, geophysical, seismological input data, as well as, in the models utilised, various interpretation schemes are applied in the PSHA analyses.

• This interpretation schemes lead to opinion discrepancies among specialists which finally lead to disagreements in estimating the values of the seismic design for a given site.
