Abstract Ground shaking, whether it is due to natural or induced earthquakes, has always been a matter of concern since correlates with structural/non-structural damage and can culminate in human anxiety. Industrial activities such as water injection, gas sequestration waste fluid disposals, promote seismicity consequent ground shaking that hinder ongoing activities. Therefore, keeping mind the...

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...
