چكيده فارسي :
Quantification of spatial correlation of ground motion intensity measures plays an important role in seismic risk assessment of lifeline networks. The variability of intensity measures for a single site has been studied during the last decades. However, the probabilistic nature of spatial correlation of intra-event intensity measures over a region has received less attention. The present study investigates the uncertainty of intra-event correlation of vertical spectral accelerations (SAs) at structural periods between 0.0 and 3.0 s. The results show that the spatial correlation of intra-event of SAs may vary earthquake-to-earthquake and is dependent on earthquake magnitude.
