Accurate prediction of the intensity and variability of strong ground motions for future large earthquakes depends on our ability to simulate realistic earthquake source models. While there has been considerable progress in characterizing the complexity of earthquake ruptures, recent devastating earthquakes have exhibited rather unexpected behavior. Moderate-size events occurred with surprising...

In violent earthquakes, ground motion is considered to change dramatically in the process of spatial propagation. Strong spatially varying exists near fault area, and it can cause large-span large stiffness structure be damaged. this paper, a typical long-span steel box arch bridge selected as an engineering case. order simulate variation accurately, records that sampled former earthquake are u...
