 Effect of aftershock intensity on seismic collapse fragilitiesNegar Nazari, John W. Van de Lindt and Yue Li International Journal of Reliability and Safety, 2014, vol. 8, issue 2/3/4, 174-195 Abstract: This paper presents a procedure to compute the sensitivity of a mainshock (MS)-damaged building's collapse probability to earthquake intensity as a function of magnitude or site-to-source distance. Specifically, the effect of earthquake magnitude and spatial distribution of aftershocks on collapse fragilities is investigated. Aftershock (AS) fragilities for different site-to-source distances are examined by performing incremental dynamic analysis (IDA) using a sequence of MS+AS ground motions. The effect of MS damage is to alter the fragilities which can be quantified for the building investigated. It is observed that the collapse fragilities have a reasonable variation in collapse probabilities with changing AS magnitude and/or site-to-source distance.
