DOI: 10.1007/s10518-020-00950-9
Abstract: Earthquake-induced pulse-like ground motions are often observed in near-source conditions due to forward-directivity. Recent worldwide earthquakes have emphasised the severe damage potential of such pulse-like ground motions. This paper introduces a framework to quantify the… read more here.

DOI: 10.1007/s10518-020-01002-y
Abstract: Long bridges and other lifeline systems are particularly susceptible to the spatial variability of earthquake actions. Even though it is a matter that has been substantially studied in the past decades, there are still plenty… read more here.
