This involves analyzing the well-known but difficult first-passage failure problem. Failure analysis is also carried out using results from Subset Simulation which yields information about the probable scenarios that may occur in case of failure. The results show that for given magnitude and epicentral distance (which are related to the ‘intensity’ of shaking), the probable mode of failure is due to a ‘resonance effect.’ On the other hand, when the magnitude and epicentral distance are considered to be uncertain, the probable failure mode corresponds to the occurrence of ‘large-magnitude, small epicentral distance’ earthquakes. 000004779 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004779 653__ $$aFirst passage problem, Markov Chain Monte Carlo simulation, reliability, Subset Simulation, seismic risk 000004779 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004779 720__ $$aAu, Siu-Kui$$iBeck, James L. 000004779 8560_ $$ffischerc@itam.cas.cz 000004779 8564_ $$s379616$$uhttps://invenio.itam.cas.cz/record/4779/files/326.pdf$$yOriginal version of the author's contribution as presented on CD, . 000004779 962__ $$r4594 000004779 980__ $$aPAPER
