Fling-step effect
WebSubsequently, the effect of fling-step was removed from the primary waveforms and the same SDOF system was subjected to the new ground motion record (without fling-step). Figure 5. Comparison of response of SDOF (T 1 =2.0 sec and R=5) to HVSC earthquake record with & without fling-step (wf: with fing-step; wof: without fling-step effect)

WebFling is the engineering term for the effects of the permanent tectonic offset, caused by a rupturing fault in the recorded ground motions near the fault. It is expressed by a one‐sided pulse in ground velocity and a nonzero final displacement at the end of shaking. Standard processing of earthquake time histories removes some of the fling effects that may be … WebJul 1, 2024 · Indeed, the effect of fling-pulses on structures and infrastructures is a topic of current engineering research, as highlighted by several studies that demonstrate the detrimental effect of impulsive ground motions on the seismic performance of structures, particularly those governed by long-periods.
WebJun 29, 2024 · Theoretically, the fling step is the contribution of the static Green’s function in the representation theorem (Hisada and Bielak, 2003), and we show that this theory holds for any seismic velocity structure. We first demonstrate the validity of this theory using theoretical solutions of a circular fault model in a homogeneous full‐space.
